1253811 IX. Description of the invention: [Technical field of the invention] The present invention relates to a communication technology and a receiving technology, and more particularly to a method and device for transmitting signals transmitted by a plurality of antennas, a receiving method and a skirting device, and the use thereof Communication methods such as methods and devices. [Prior Art] In wireless communication, it is generally expected to effectively utilize limited frequency resources. One of the techniques for effectively utilizing frequency resources is an adaptive array, an adaptive array antenna technology. The adaptive array antenna technology controls the amplitude and phase of the signal transmitted and received by a plurality of antennas to form an antenna-oriented mode. That is, the device having the adaptive array antenna is configured to change the amplitude and phase of the signal received by the plurality of antennas separately, and separately add the plurality of received signals after the change to receive the 盥, The amount of change in amplitude and phase (hereinafter referred to as the signal equal to the signal received by the antenna in the weighted mode). Then, the signal is transmitted according to the directivity mode of the corresponding weighted antenna. In the adaptive array antenna technique, in the processing example for calculating the weighting, there is a method based on the minimum mean square error (Minimum Mean Square E: r〇r) method. In the bribe method, the condition of the weighted optimum value is provided' ::, :: (Wlener) is known as a solution, and in addition to directly solving the Wiener solution, the recursion formula is less (reeurrenee (6) and (4) is also generally known. The recursion formula is used, for example, rls(10)Least Adaptive algorithm such as _·· recursive least squares algorithm or LMSaeast MeanSquares·minimum mean square algorithm. On the other hand, 316510 5 1253811 speed and transmission quality of data transmission speed For the purpose of the improvement, the data may be multi-carrier modulated to transmit a multi-carrier signal (see, for example, Patent Document 1). [Incorporated Patent Document 1] S. Japanese Patent Application Publication No. Hei 10-21 0099 The problem to be solved is a MIMO (Multlple Input Multlple 〇utput) system in which the adaptive array antenna technology is used to speed up the data transmission speed. The ΜΙΜΟ system, its signaling device and reception The device has a plurality of antennas respectively, and sets a channel corresponding to each antenna. That is, for the communication between the transmitting device and the receiving device, the channel up to the maximum number of antennas is set to improve the data transmission speed. In addition, when the technology for transmitting a multi-carrier signal is incorporated into the above-described ΜΙΜΟ system, the data transmission speed is further accelerated. On the other hand, in order to correctly receive the signal sent by the signaling device by the receiving device, generally In the case of a signal, it contains a signal that is itself a known signal. However, the system is closed. The hole is placed at the receiving uranium signal. In some cases, the weighting of the adaptive array signal processing cannot be derived. In this case, interference occurs between the preamble signals that are rotated by the plurality of antennas, and the signal received by the receiving device is likely to be erroneous. In particular, since the setting of the AGC (Aut〇maticgain control) according to the previous pilot signal is performed in the initial stage of the reception processing, it is susceptible to the interference of the preamble signal received from the undesired antenna. In view of the above problems, the researcher aims to provide a plurality of known signals stored in a 316510 1253811, so that the number of carriers used only for the known signals corresponding to the main antenna can be larger than that used only with the secondary antennas.

In addition, as shown in the figure, the "preamble signal" of the "4 〇FM symbol" is separated into "STS (Sh〇rt Trainin °g Sequence)" and "2 0FDM symbol" of "2 OFDM symbols". "LTS (L〇ng Traini叩Sequence)". The STS system consists of: 1 unit of signal "u" to "ti〇", and 1 unit "tl" is 16 FFT points. In the above-mentioned sts, the unit in the time domain is 16 FFT points. However, in the frequency domain, the STS system uses 12 subcarriers among the 53 subcarriers shown in Fig. 1 described above. In addition, the STS' is particularly used in the setting and timing synchronization of the AGC. On the other hand, the LTS consists of two units of signals "T1" and "Ding 2" and a guard interval of two times the length rGi2". The unit "η" is 64 FFT points, and "GI2" It is a 32 FFT point. LTS, especially for the reproduction of carriers. 316510 30 1253811 The signal in the frequency domain shown in Figure 1 is displayed in s, 26.μ, and the subscript number shows the subcarrier number. When the above-described form is used, the STS of the IEEE802·1 la standard is as follows.

Here, the problem of transmitting the STS of the IEEE802·11a standard by the first transmitting antenna 14a and the second transmitting antenna 14b of Fig. 2 will be described. The signal transmitted by the first transmitting antenna 14a is set to S1(t), the signal transmitted by the second transmitting antenna 14b is set to S2 (t), and the noise is set to η 1 (t) and η2 ( When the signal X1 (t) received by the first receiving antenna 16a and the signal X 2 (t) received by the second receiving antenna 16b are not as follows [Expression 2] X1 ( t) = hi 1S1 (t) + h21 S2(t) + n1 (0 X2(t) = h12S1(t) + h22S2(t) + n2 (1) The signal received by the first receiving antenna 16a is 16 The FFT is the intensity of the unit, as shown below.

Indeed, action. In addition, in general, Xc will be reduced to 2 to 疋〇 in the data interval, so the receiving power of the data interval will form 丨h 1 1 I 2+丨h22 I 2 . Therefore, the data interval and the received power of the STS interval will be 2Re[hUh*2ix c] as shown in the third item on the right side of (Expression 4). As is apparent from the following, even if ^(^ and "(., at the same time, when the Xc of the sts section is large, the power of the STS section and the power of the data section are greatly different, so the AGC cannot perform normal operation. Therefore, for the system, other sts's that differ from the IEEE8〇2.Ua specification are required and the correlation (cr〇ss_c〇rreiati〇n) must be low.

The radio unit 50 receives the signal, and the AGC 66 sets the AGC based on the STS included in the received signal (S1 0). As a result of the correlation processing obtained by the correlation unit 70, when the control unit 58 can detect the STS (Y of S12), the input-1 determines the allocation amount of the transmitted complex signal by the processing unit 52 and the demodulation unit 54 (S14). ). On the other hand, when the control unit 58 cannot detect the STS (N of S12), the door returns to the step 1〇 again. The processing unit 52 starts the adaptive array signal processing (S16) by deriving the received weighting signal 2〇6 based on the LTS in the received signal. The demodulation unit 54 demodulates the synthesized signal outputted by the data combining unit 56 (S18). According to an embodiment of the present invention, among a plurality of predetermined subcarriers, since different subcarriers are used in a plurality of known signals, the mutual correlation between a small number of known signals is reduced by 316510 40 1253811. In addition, since the correlation between the plurality of known signals is small, the accuracy of detecting a plurality of known signals of the receiving device can be improved. In addition, since the mutual correlation between the plurality of known signals is small, the accuracy of setting the AGC by the receiving device can be improved. (Second Embodiment) A second embodiment of the present invention is the same as the first embodiment of the present invention, and relates to a preamble applied to the MIM0 system for the purpose of reducing interference between the transmitted (four) preamble signals. In the third embodiment, in order to make the mutual correlation between the plurality of preamble signals "Q", the subcarriers for which the respective preamble signals are allocated are inconsistent, and the number of subcarriers to which each preamble signal should be allocated is the same as f2. For example, the transmitting device does not set the number of carriers to be assigned to each month. The number of carriers to be used is the same number, that is, the number of subcarriers to be allocated is more than one, and one pilot signal is used. The fewer subcarriers are assigned to other preambles, and the self-correlation value will produce a difference in the preamble unit. The transmitting device 1 收 and the receiving device 丨2 of the second yoke example are the same as the receiving device i 2 of the transmitting device i 〇 and 帛 5 of the f 4 example of the first embodiment, and therefore are omitted. Its description. - In the embodiment of the mutton 1 , the number of subcarriers allocated to each STS is set to the same number. As a result, the correlation between the two can be made small, and the mouth of the AM can be improved. In addition, since the number of subcarriers per i STS becomes small, the self-correlation of (10) t is also small. On the other hand, since the order of the receiving device 1 2 and the frequency offset (not shown) are estimated based on the self-correlation of ^, therefore, the self-correlation of the STS is generally The detection accuracy and estimation accuracy also become higher. That is, in the 316510 1253811; two = embodiment, it is stipulated that: corresponding to the multiple of the fourth figure = day, the self-related characteristic of one of the caps is higher than that of the ^^^ days... The self-related characteristics of STS. In addition, it is also assumed that the number of the 'waves' used for the one of the plurality of transmitting antennas 14 is higher than the number of subcarriers that should be used for the other transmitting antennas and 匕1S. Comment: In the body, the transmitting device 10 is provided with three transmitting antennas. 14 Wei 2: When only the first transmitting antenna 14a and the second transmitting antenna (10) are dedicated to the tiger, the system will The subcarriers are allocated to the corresponding first antenna ts, and the six subcarriers are allocated to the corresponding second antenna. On the other hand, when three transmission antennas are used to transmit signals, = 6 subcarriers are allocated to s τ s corresponding to the second transmitting antenna 丨 4 a , and subcarriers are allocated to corresponding second transmissions With the antenna (10), three subcarriers are allocated to the corresponding third transmitting antenna A, and the receiving device f12 of Fig. 5 can be set according to each grab. Further, the receiving device 12 performs timing detection and frequency offset estimation based on the STS having the largest number of subcarriers in the plurality of STSs. In other embodiments of the second embodiment, the (four) wave portions used by different STSs are repeated. Compared with the past embodiments, although the correlation becomes larger, the self-correlation also becomes larger at the same time. In other words, among the plurality of subcarriers used in the STS defined by the IEEE802.11a standard, only the number of still subcarriers of the plurality of transmitting antennas 14 is set to be the first and only When the number of field 1J carriers used for Ms corresponding to other transmitting antennas is set to the second value, 'the plural number is still set to the first 3) 6510 1253811 The value must be greater than the second value. For example, 8 subcarriers are assigned to the corresponding modulo. The fl uses the STS of the antenna 14a, and the six subcarriers are allocated to the STS day temple corresponding to the second transmitting antenna 14b, and two subcarriers are repeated. Further, when the number of the transmitting antennas 14 is three, the second value is set to be the number of sub-carriers used only for one of the other transmitting antennas 14. In the above case, it is defined as the STS of the second transmitting antenna ub and the third transmitting antenna 14c and the corresponding i-th transmitting antenna! The cross-correlation property between sts of 乜 is lower than the correlation between the STS corresponding to the second transmitting antenna Mb and the STS corresponding to the third transmitting antenna Uc. That is, the STSs corresponding to the three transmitting antennas 14 are all six subcarriers, but one of them exclusively uses four subcarriers, the other one exclusively uses two subcarriers, and the other one does not monopolize. Use all subcarriers. Further, the assignable subcarrier sets the second value to "〇". In other words, the six subcarriers are exclusively allocated to the STS corresponding to the second transmitting antenna 14a, and correspond to the second transmitting antenna Ub, the third transmitting day, and the STS of Table 14c, respectively. The remaining β subcarriers are shared. At this time, the STS described above uses a series of signals whose correlation is reduced. According to an embodiment of the present invention, in a predetermined subcarrier, the number of subcarriers respectively used in a plurality of known signals is different in a plurality of known signals, so that a plurality of known signals can be designed to make self-correlation Or values that are related to each other become a predetermined value. In addition, since the self-correlation value corresponding to the predetermined known signal is increased, the timing detection of the receiving device = the accuracy of the accuracy and the frequency offset can be improved. 316510 1253811 (3rd embodiment) The third embodiment of the present invention is the same as the first embodiment of the present invention. However, the third embodiment relates to the related processing in the receiving device. As described above, when a plurality of antennas of the transmitting device transmit a plurality of known signals in a sub-mode, the receiving device must use a plurality of corresponding signals in order to detect the timing from the plurality of known signals received. A plurality of correlators of each of them. Here, having a plurality of correlations will result in a larger circuit scale of the receiving device. The surface system of the present embodiment is a series of known signals in the time domain (below, The plural relationship between the plurality of "time domain known signals" is defined as a predetermined relationship. The transmitting device transmits the plurality of known time domain known signals, and the receiving device, the root, and the plurality of time domains have known relationship between the signals to reduce the processing of the related processing. That is to say, in general, the correlation processing is performed by multiplication and addition. In the present embodiment, in the correlation processing of the series of two known signals, the multiplication is common and different. The combination is added to the multiplication result, and two correlation values are rotated. The transmitting device 1 and the receiving device 12 of the third embodiment are the same as the transmitting device i 0 of the fourth embodiment of the summer embodiment and the receiving device i 2 of the fifth embodiment, and therefore the description thereof will be omitted.

In the present embodiment, the processing up to the output of the second correlation in-phase value 214 and the second correlation in-phase value 216 is the same as the processing of the 13th graph up to the output: the value 214 is the same as the second correlation in-phase value 21 6 Therefore, the processing of the in-phase value 210 and the second correlation positive = straight 316510 50 1253811 21 6 is omitted, and the multiplication unit 3丨4 corresponds to the delayed third baseband reception signal 202a. The value of the multiplicative memory unit 304 and the value of the Q memory unit 306. However, only the eleventh memory unit 304a and the 31st memory unit 304c are used in the I memory unit. In other words, the multiplication unit 314 that performs the multiplication using the I memory unit 304 is in the order of the time series, the second multiplication unit 314b, the sixth multiplication unit 314f, the tenth multiplication unit 314j, and the fourteenth multiplication unit. 314η juxtaposed. The second multiplying unit 314b performs multiplication using the eleventh storage unit. However, the sixth multiplying unit 31 performs multiplication using the 31st storage unit 3b without using the 21st storage unit 304b. That is, i is the period of the first time domain STS and the second time domain STS, and in this case, the value of 1 /2 is reciprocal, that is, the value of the I memory unit 304 is selected in accordance with an integer of, for example, "2". The same is true in the Q memory department. According to the embodiment of the present invention, by using the delay portion for delaying the input signal for the reference signal of the complex number, the memory portion storing the reference signal is shared, so that the circuit scale can be reduced. (Embodiment 5 embodiment): The fifth embodiment is the same as the third embodiment, and is a process related to clothing. In the plurality of (4) fields of the present embodiment, the square of the known portion, the in-phase component and the orthogonal component are 〇, and a waveform having a constant amplitude is formed. In addition, the other of the known signals in the field of timekeeping forms a value that reverses the orthogonal component of one of the parties. Receiving the receiving device with the known time in the above-mentioned time domain 41, in addition to being able to share the part of the related processing that is known in the two time domains, the multiplication can also be omitted. The waveform of the known signal transmitted by the transmitting device 10 of the fifth 杳a, which is known by the $b, is displayed. Here, the number of the antennas 14 is set to 316510 51 1253811 3, corresponding to the first The STS system of the transmitting antenna 14a is disposed in the subcarrier number "-24" _20 '12', 8, 4, 4, 8, 12, 2, M", corresponding to the second transmitting antenna 14b. The STS is placed in the subcarrier number "_16", and the ST corresponding to the third transmitting antenna 14c is placed in the subcarrier number factory. Fig. 16 shows a time domain STS corresponding to sts of the second transmitting antenna 14b. On the other hand, in the time domain STS corresponding to the sts of the third transmitting antenna l4c, a waveform 0 = 17 in which the orthogonal components of Fig. 16 are inverted is formed, and the correlation portion 7 of the fifth embodiment is displayed. The composition of cockroaches. With respect to the correlation unit 70 of Fig. 13, the correlation unit 7 includes the first inversion unit 318a, the second inversion unit 31, the second object portion 318c, and the fourth inversion, which are collectively referred to as the inversion unit 318. Part 318d, fifth inversion part, sixth inversion; 31 8 f. The inversion unit 318 reverses the value of the input signal. That is, the positive value is exchanged for a negative value, and the negative value is converted to a positive value. Addition unit 312, add the first!

In the embodiment of the present invention, the circuit scale can be reduced by substituting the complex reference signal i: two for delaying the input of the input signal and the multiplication unit in (4). (Embodiment 6) The same as the previous embodiment. The sixth embodiment of the present invention relates to the 316510 52 1253811 ΜΙΜΟ system. As mentioned earlier, the ΜΙΜΟ system transmits separate signals from a plurality of transmitting antennas. In the previous embodiment, the number of transmitting antennas was fixed at a constant value. However, the number of transmitting antennas may be changed in accordance with the capacity of the data to be transmitted. That is, the amount of transmitting antennas can be reduced when the capacity of the data to be transmitted is small. The reverse is that the capacity of the data to be transmitted can increase the number of transmitting antennas. When the transmitting device appropriately changes the number of transmitting antennas for transmitting signals, the receiving device corrects the data. The number of transmitting antennas that have been changed must be recognized. When the transmitting device notifies the receiving device of the number 1 of the transmitting antennas for transmitting data based on the predetermined signal, the transmitting device may reduce the data transmission efficiency due to the control signal. 2::W is best to identify the number of antennas used for transmission >'s transmission without control signals. The transmitting device of the embodiment of the disc 2 identifies the number of transmitting antennas for transmitting data based on the mode ST' of the transmitting antenna STS and the STS mode of the transmitted data, and the receiving device 'detects the changed mode of ' . In other words, the number of antennas to be transmitted is divided into one (hereinafter referred to as "main antenna" and the rest (hereinafter, the number of "," is changed to the main day ^彳t". The mode of the transmitted STS. In addition, in order to receive the ST9 ... transmitted by the main antenna, the ST is connected to the TS, and in the STS of the main day ... and the sub-antenna are transmitted, and the STS is separately specified. Let the different subcarriers be used in the other sub-S. Also, the cross-correlation value between the two is reduced. In the embodiment, the mode of the STS is sent, and the detection of the STS is sent by the main antenna. STS 杈 type of related processing, no storage. For example, the number of transmitting antennas is 316510 53 1253811 ¥ 'There must be a corresponding part of each $ ffl type. In this embodiment, ^ 疋 疋The mode with the number of antennas will be the third real; __inch's the STS system transmitted by the main antenna. Therefore, the correlation between the reciprocating positions of the receiving and receiving devices is measured by the relevant part of the main antenna. The Japanese temple can be used to check the mode change of the STS sent by 斟广々. In addition, it will benefit and remove the pattern of the bribes. Section. I and with

Then, = 2 = :, the modulation of the number of antennas 14 is used to transmit signals. The signal adding unit 32 stores sts or coffee in advance as described above. M2, the antenna for the transmission determined by the center of the heart (4) Eight of the STSs stored in advance are selected to be predetermined. For example, scoop 2: the preamble signal adding portion of the modulation unit 22 of the main antenna: = the main antenna. In addition, corresponding to the main antenna, it is stored according to the number of antennas 14 for the transmission, and the number of transmission days and lines 14 corresponding to the decision is selected. For example, it can be determined that the transmitting antenna = 3165] 〇 54 χ 253811 when the number is "2" or "3, the number of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In addition, when the number of antennas for the corresponding transmitting antenna is "3", the number of transmitting antennas 14 determined by the leading and the pin is "2". (1) The additional portion u is added to the burst signal. In addition, the STS of the w" is added, and the path L of the modulation unit 22 attached thereto is one or more of the corresponding sub-antennas, and the signal addition unit 32, STS. When the secondary antenna is a complex number, the =select=toring line is different to reduce mutual interference. The addition of the mouth and the younger brother 18 shows the transmission of the 箆a ^ 14 teaching life I brother 6 Bei Yuan case of the poor material of the communication antenna several people each use the antenna 14 to transmit the STS y 4 11 6^7 ^ ^ ^ The relationship of the bTS. Here, the number of antennas is 14 days, and the horizontal direction of the picture is the sum of money: "The antenna for transmission and the STS corresponding to each antenna. That is, the number of antennas 14 for transmission is Γ1. At the time of transmission, the worker's transmission antenna 14a transmits the "Ugacy STS" defined by the above-mentioned dirty 〇2Ua specification. In addition, the number of the transmitting antennas 14 is 2, and the "2" is transmitted by the first transmitting antenna, and the value of the second transmitting antenna 14b is "STh, .a ^ R md. 6lba When the number of the transmitting antennas 14 is "3", "STS1" is transmitted from the first transmitting antenna Ua, "STS2" is transmitted from the second transmitting antenna 14b, and the third transmitting antenna 14c is transmitted. Send "STSb". Here, the second transmitting antenna 14b when the number of transmitting antennas 14 is "2" and the third transmitting antenna 14c when the number of transmitting antennas 14 is "3" corresponds to the main antenna ' The other antennas are equivalent to the secondary antennas. In addition, according to the previous description, the STS of the main antenna when the number of the corresponding transmitting antennas 14 is "2" is "STSa", and the number of corresponding transmitting antennas 为4 is 316510 55 1253811 "3" when the main antenna is STS is "STSb". On the other hand, the STS of the sub-antenna when the number of the transmitting antennas 14 is "2" is r STS1", and the STS of the sub-antennas when the number of the transmitting antennas 14 is "3" is "STS1" and "STS2". "." In addition, for convenience of explanation, "STSa" and "STSb" are collectively referred to as "STS for main antenna", and "STS1" and "STS2" are collectively referred to as "STS for sub antenna". In addition, the case where the number of transmitting antennas i 4 of the transmission signal is "2" or "3" will be described here, but the number may be a number other than 2 or 3. In describing the relationship between the STS and the legacy STS, it is stipulated that a plurality of carriers for the STS for the primary antenna and the STS for the secondary antenna should be used, and one of the 12 subcarriers of the Legacy STS should be used. Here, the STS for the primary antenna and the STS for the secondary antenna use six subcarriers different from each other among the 12 钊 carriers of the Legacy STS. According to the above rule, the correlation value between the STS for the main antenna and the STS for the sub antenna becomes "〇". In addition, the six subcarriers used by the STS for the main antenna are not affected by the number of transmitting antennas 4 of the transmitted data, and the β subcarriers used by the STS for the main antenna are not transmitted. The use of the news is maintained by the influence of the number of springs. Therefore, when the number of antennas 14 having a plurality of sub-antennas is set to "3", "STS 1" and "STS2" use six subcarriers in the same manner. The STS for the main antenna includes "STSa" and "STSb", but the "STSa" and "STSb" modes are different, and the number of the transmitting antennas 14 for transmitting the signal is notified to the receiving device 丨2. The function. Therefore, in order for the receiving device 12 to distinguish between "STSa" and "lamp" via the received signal, the STS described in 316510 1253811 must be different. That is, when the number of the main antenna STS is different between the number of transmitting antennas 14 to be transmitted, the STS is different for the main antenna, and more specifically, between "STSa" and "STSb". The value of the cross-correlation property is reduced to be specified. Further, the above specific values will be described later in detail. On the other hand, the STS for the sub-antenna, especially when the sub-antenna is a complex number, uses the same sub-carrier by the ash system. Therefore, "STS1" and "STS2" are defined in the 可使 type in which the interference between the antennas is reduced. The STS for the secondary antenna is defined by a value which makes the mutual correlation characteristics smaller. According to the above, even if the number of transmission antennas 14 used for signal transmission increases, the number of carriers used for the main antenna is fixed at "6", and the number of subcarriers used for only one sub-antenna STS is reduced. To "〇". , ^ Ί 9 diagram, _ shows the waveform of STSa, Figure 20 shows the wave of STSb:. In other words, the values of the time domain of the STS for the main antenna when the number of the transmitting antennas 14 for transmitting signals is "-3" and the STS for the =, in the time domain, have the in-phase component and The orthogonal component "' corresponds to two values of the antenna to which the signal should be transmitted, that is, Γ2 and "3", and the value of the in-phase component of "stq" 〆, a" is equal to the value of the orthogonal component of "STSb", and The value of the positive component of "QTQ. ^ x lba" is equal to the phase of "STSb"

However, in the eighth embodiment, the number of the antennas for the transmission of m", that is, the number of antennas to be transmitted, is also described. Here, when the number of transmitting antennas is one, it is set to the wireless UN based on the IEEE802.11a specification, and the STS system corresponding to the above-mentioned benefit line is set to LegacySTS. The signaling device transmits LegacysTS, STSa, and STSb from the main antenna based on the number of transmitting antennas for transmitting data. Further, as described above, the Legacy STs uses 12 subcarriers, and the STSa and STSb use β subcarriers. 316510 63 1253811 On the other hand, the receiving device has a correlation unit corresponding to the Legacy STS and the STSa STSb, respectively, for performing phase processing with the received signal to respectively output the correlation value. Next, the size of the correlation value is compared and the number of STS specific signaling antennas having the largest correlation value is compared. In the embodiment of the present invention, the relevant part of the Legacy STS does not maintain the value of the Legacy STS corresponding to 12 subcarriers, but selects the STSa, STSb in the ... of the i subcarriers. 6 subcarriers, while maintaining the value of the subcarrier corresponding to the selection. Fig. 27 shows the configuration of the relevant portion 7A of the eighth embodiment. The correlation unit 7'' includes a related section for the Legacy STS, a correlation unit 332, an STSb correlation unit 334, and a selection unit 336. Further, the relevant portion of the corresponding sub-antenna may be provided, but it is omitted here. The STSa correlation unit 332 stores in advance a number of signals in the time domain and calculates a correlation value between the stored signal and the received signal, which is referred to as "2 antenna correlation value". The coffee-related party stores a plurality of signals for converting the STSb in the time domain, and calculates a correlation value between the stored signal and the received signal (hereinafter referred to as "3 antenna: correlation value"). In the present embodiment, the sts^ correlation unit 332 and the STSb correlation unit 334 are described in another configuration. However, the first correlation unit 70 may be configured as in the sixth embodiment. ,

The Legacy STS correlation unit 330 pre-stores a signal in which only the subcarrier signals used in the STSa and STSb are converted in time. Then, the Legacy STS uses the correlation unit 33〇 to calculate the correlation value between the stored signal and the received signal (hereinafter referred to as "丨 antenna: phase 316510 64 1253811 OFF value").

In addition, since the accuracy of the correlation value to be compared can be improved, the estimation accuracy of the number of antennas for transmitting and transmitting signals can be improved. In addition, the above correlation = use in the detection of timing, and the like. (Ninth Embodiment) A ninth embodiment of the present invention, and the present invention relates to the application to the MI system.

It is about the configuration of the preamble signal, even if it is in the frequency selection;; it can also improve the gain control accuracy of the AGC, and the attenuation of the selective attenuation of the fly rate will be attenuated in the signal (10). Department; with higher frequency to higher frequency, the signal attenuation is larger: column, by: alternately appears. In the above operation, the subcarrier of the multi-rate of Nagasaki is transmitted to the subcarrier of the high frequency, and the attenuation of the subcarrier by the low pair of predetermined numbers becomes larger, and the attenuation of the subcarrier is reduced. 。 汛唬 预定 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 538 12 12 12 12 538 12 12 12 12 12 12 12 12 12 12 12 Even if the STS transmitted by each antenna is relatively correlated with each other, only the field 丨J carrier is used, that is, if a boring <subcarrier and minimum subcarrier 4' is used: the maximum frequency is used in the subcarrier.

This is because the increase in the number of subcarriers is increased. The situation and the situation where the signal strength is reduced. The STS of the plurality of antennas of the embodiment uses only a predetermined number of subcarriers selected in the off-channel manner. For example, subcarriers separated by number 8 are used. Thus, even if the number of subcarriers carried by the substation of the STS is STS can also be used in the overall signal eve.

In the above manner, if the number of subcarriers used by the Japanese syllabus is smaller than the number of sigma used in the data, the appropriate gain can be derived in the frequency selective fading environment. In addition, 316510 66 1253811 The arrangement of the first embodiment and the like is the same as that of the first embodiment and the like, and the transmitting device 丨° and the receiving device 12 of the ninth embodiment are the same as the fourth picture of the first example of the palladium. Therefore, the description thereof is omitted. Figs. 28(a) to 4(4) are schematic diagrams showing known signals of the subcarriers arranged in the ninth embodiment. Figure 28 (showing the lack of people - people, ^ ang i map is the same ==... is the corresponding subcarrier number, the vertical axis corresponds to the signal transmission ^, the line table material is the job wave (four), the dotted line is like the frequency selection The effect of the attenuation is as shown in the figure - the signal strength part.

If the signal is transmitted by the corresponding device 1 (), the signal attenuation is small. Therefore, the 5 received by the receiving device 12 will become larger. Japanese] Tiger strength 316510 67 1253811 In addition, Figure 28 (b) shows the same situation as Figure 28 (a) In this case, the subcarriers of the STS transmitted by the second transmitting antenna 14b are arranged. Here, the carrier number is a subcarrier using r丨7_2〇". Here, as shown in Fig. 8(a), The receiving i is set to 12, and the received signal strength is larger than sts. VIII, 'σ fruit /, to STS in accordance with Figure 28 (a) and (b) configuration, receiving clothes 12, will be based on signal strength If the gain is set to 6, the gain value will be smaller. However, as shown in the figure, in the frequency term field corresponding to the "4_17" subcarrier number, the signal attenuation in the transmission path will become larger. The signal strength of the subcarrier data in the ηHai frequency domain is smaller than that of the STS. That is, the value of the gain set according to the STS is smaller than the value suitable for the gain of the transmission function, and thus sometimes received. An error occurs in the signal. Fig. 28(c) shows the arrangement of the subcarriers of the sts transmitted by the i-th transmitting antenna i4a of the present embodiment. As shown in the figure, the STS uses a plurality of subcarriers. The predetermined number of subcarriers selected in a discrete manner, that is, used by 20 Among the subcarriers, each of the five selected 4 carriers is the carrier. The corresponding subcarrier numbers are "5", "1", "1 5", and "20^. In addition, the frequency bandwidth is equivalent to the number of subcarriers. The frequency band of 15. The code is "3" and "28" (d), and shows the arrangement of the subcarriers of the STS transmitted by the second transmitting antenna 14b in the same case as Fig. 28(c). Μ Figure (4)' is the same as Figure 28 (c), using 4 subcarriers selected from 5 out of 2 subcarriers. However, the corresponding subcarrier number 13 is the first. The transmitting antenna 18 slave 5, eight, 14a transmitted by the sun and transmitted by the second transmitting antenna (10) 336510 68 1253811 STS ir, using * the same subcarrier. This is to reduce the interrelationship between the I and the I. On the other hand, it is equal to the frequency bandwidth in the STS transmitted by the first transmitting antenna 14a. In Fig. 28(C), the signal corresponding to the wave of the subcarrier number "5" and "1〇" becomes a female, and the &amp; M e is a large number and corresponds to the subcarrier numbers "10" and "15". The signal strength of the subcarrier becomes smaller. In addition, in Fig. 28 (4), the signal strength of the carrier corresponding to the sub-two-wave number "3丨, "18丨之之之田战" field] becomes larger, and corresponds to the sub-load; ^码8", "13 The signal strength of the subcarrier becomes smaller. The subcarrier configuration 'includes subcarriers with increased signal strength and subcarriers with reduced signal strength. 2 This situation will qualitatively reflect the frequency selective attenuation environment: '刖=number. Therefore, if the subcarrier configuration is based on (e) and (4) of Fig. 28, the value = profit will be close to the gain value suitable for the transfer function. As a result, errors occurring in the received signal can be reduced. - According to the presentation of the IMO system, the number of turns of the brothers, such as the STS system, is configured as a subcarrier. The first transmission uses the sub-carrier numbers "-24", "-16", "_8", |4", "12", "2" subcarriers, and the positive j-carrier transmitted by the second transmitting antenna 14b. The numbers "-20", "-12", "-4", "δ", "ΐ6", "24, ^ wave. In addition, in addition to this, you can also open the "Taiwan" sunset. _ Drinking from the configuration shown in Equation 10 of the L example, the STS' is as described above. In the embodiment of the present invention, even in the case of frequency selective attenuation production, it is also possible to provide a comparison between the preamble signals in the plurality of antennas before the estimation accuracy of the gain is improved. In addition, Burley is related. In addition, the 31 series 316510 69 1253811, which is continuously transmitted by your antennas and antennas 14 , has fewer sub-residues for the signal used, so the signal period of the time collar can be shortened. In addition, the gain estimation can be speeded up accordingly. Since the gain can be increased, the quality of the received signal can be improved.
