Assistants, PDAs, personal computers, laptops, home devices, etc., connect directly or indirectly to other wireless communication devices. For direct communication (also known as point-to-point ittfl) 'synthesis wireless fine touches it to find the transmitter and transmitter to the same channel (for example, the number of radio frequencies in the wireless communication system, Frequency), ^) One of the carriers) and communicates on the poor road. For direct wireless communication, each wireless communication device communicates directly with a related base station (basestationX, for example, mobile device) and a related network bridge 1305090 with a specified channel via a designated channel. Patterned into the wireless cable ^2 connection 'the associated base station and / or related network bridge Ϊ ^ inspection 11, public __ network, tank _ and / or - this eight wide area ( Wuie area) The network is directly connected to each other.

The heart i has a county s hot track ginseng _ silk secret, the wireless communication is set to ^ 咖 ι ί wireless transceiver (that is, the receiver and transmitter run consuming c wireless transceiver (such as a home or building without _ network,,, number f turn). As you know, the receiver is lightly coupled to - secret: the receiver includes a low-sound file, one or a plurality of intermediate frequency levels, Miscellaneous "level and a poor material recovery level. The low noise amplifier receives the interface of the connection (four) through the antenna Wei Zhao Wei Da. The - the relatives of the relatives "large RF shouts and - a few dollars The machine oscillates and mixes to convert the RF signal to the baseband signal or the intermediate frequency (Intermediate F). The filter ship reads the unwanted frequency band = track number, thereby generating a filtered signal. The data recovery level recovers the original data corresponding to the special wireless communication standard from the signal. Also, as is known, a transmitter includes a pie adjustment level, = one or plural, and a Amplifier. H side section (10) was originally funded, replaced with a special wireless pass Standard consistent baseband signal. The one or more. The intermediate frequency stage mixes the baseband signal with one or more local oscillators to generate an RF signal. The resolution is greater than the antenna transmission. The transmitter will include an antenna for transmitting the RF signal. The frequency signal is received by a single antenna or a plurality of antennas of a receiver. The g δ receiving state includes two or more antennas. Yes, the receiver will select one of them to receive the incoming RF signal. In this example, the wireless role between the transmitter and the receiver is the H output single-input (Singk 〇U(4) Single Input, SOSI) The communication 'even if the receiver includes being used as multiple types of 1305090 to receive the incoming RF signal.) For the 2nd and 2nd transmission * Early * 7 input communication '- a transceiver includes one transmitter and one connection Benefits. Currently, most wireless local area networks are single-output single-input wireless ports that use (four) ee 正 ee f.lla, IEEE 802.11b or IEEE 802.1 lg. One input multiple output (s bee mail test ult_ 〇_, siM〇), multiple input single output __ 〇u_, MSO) and multiple input multiple output __ but hungry ιι__〇_ι Γ^ΙΜ^). In one A single input/output multi-output wireless communication towel, a single transmitter, processing data into an RF signal transmitted to a receiver. The receiver includes two or more antennas and two or more receiver channels. The frequency signals are provided to the responding receiver channel (eg, LN== group: filter and ADCs). Each receiver channel processes the RF signal to generate a digital signal. The digital signal can be combined and then Process to retrieve the transmitted material. For a multi-input single-output wireless communication, the transmitter includes two or more transmission channels (eg, digital analog converters, filters, up-conversion modules, and power amplifiers), each channel will have a baseband signal The corresponding part is converted into an RF signal. The RF signal is transmitted to a receiver through the corresponding antenna. The receiver includes a single receiver channel that receives a plurality of RF signals from the transmitter. In this example, the transmitter combines the plurality of radio signals into a single signal by the formed electron beam. For a multiple input multiple input wireless communication, each transmitter and receiver includes a plurality of channels. In such communications, the transmitter uses spatial and temporal coding to process data in parallel to produce two or more data streams. The transmitter includes a plurality of transmission channels to convert each data stream into a plurality of radio frequency scent. The receiver receives the plurality of RF signals through a plurality of receiver channels, and uses a spatial and temporal decoding function to retrieve the data flow. The retrieved data flow 1305090 is combined and subsequently processed to restore the original data. It is desirable to use a variety or type of wireless communication for different types of wireless communications (e.g., SISO, MISO, SIMO, and ΜΙΜΟ) to enhance the net data throughput. For example, compared to a single input from a single pass, the high data rate can be achieved by multiple input multiple output communication. However, most wireless devices include traditional scale communication devices (that is, devices that adapt to an older version of the wireless communication standard). Because of this, the purchase of a multi-input multi-round communication should also be compatible with the traditional equipment of the financial scale area _ most functions. =地,#—A lung is a turn of Wei, the code of the hair (4) lion is 1 m 4 ’ because the small constellation adopts a channel of 2〇2

Note that the lengths of the inverse fast Fourier transform and the head of the loop are defined in the pattern table of table i_12. Typically, a 64-point fast Fourier inverse transform is applied to the 20 MHz channel and the 128-point fast Fourier inverse transform is applied to the 40 MHz channel. The space/time encoder 192 receives the time domain characters of the two parallel channels and converts them into one output word. In one embodiment, the number of 25 1305090 of the one output channel is equal to the number of p wheeled channels.

The number of radio channels corresponding to the number of ρ outputs is generated by the crying and 甫 output channels, and only the number of radio transmitting channels can be selected from the range of 丨 to any desired number. The digital filtering/upsampling module 194_198 filters the corresponding character and adjusts the sampling rate corresponding to the desired sampling rate of the digital analog conversion module track 2〇4. The digital analog conversion mode 'group 200_204 converts the digitally filtered, wave upsampled signals into corresponding in-phase and quadrature analog signals. The analog chopper 2〇6_216 filters the corresponding in-phase and/or quadrature portions of the analog signal and provides the filtered signal to the corresponding I/Q s-circulator 218_222. The ΐ/Q modulator 218_222 oscillates a local oscillator oscillated by the local oscillator 100, and upconverts the Μ signal into a radio frequency signal. The RF amplifiers 224-228 amplify the RF signals, and the surface signals are then filtered by the RF filters 230-234 and transmitted by the antennas 236-240. Figures 11A and 11B are block schematic illustrations of another embodiment of the receiver of the present invention. Figure 11A shows the analog portion of the receiver, which includes a plurality of receive channels. 26 1305090 Each receive channel includes an antenna, RF filters 252-256, low noise amplifiers 258-260, I/Q demodulator 264-268, analog filters 270-280, analog digital converters 282-286, and Digital filtering/downsampling module 288-290. In operation, the antenna receives the returned RF signal filtered by the RF filter 252-256. The corresponding low noise amplifiers 258-260 amplify the filtered signals and provide them to respective I/Q demodulators 264-268. The I/Q demodulator 264-268 converts the RF signal into an in-phase and quadrature baseband analog signal based on a local oscillation generated by the local oscillator. The corresponding analog filter 270-280 filters the corresponding in-phase and/or quadrature portions of the analog signal. The analog to digital converter 282_286 converts the in-phase and quadrature baseband analog signals into digital signals. The digital filtering/downsampling module 288-290 filters the digital signal and adjusts the sampling rate to correspond to the code rate of the baseband processing (described in Figure 11B). Figure 11B shows the baseband processing of a receiver. The baseband processing module includes a space/time array δ horse 294, a plurality of fast Fourier transforms (Fourier Transform IFFT), a loop head initial adding module 296_3 〇〇, and a plurality of character demapping modes.

By adding the external Reed-Solomon encoder, the coding gain - that is, the lower signal alpha ratio of the same frame error rate - is achieved. The Lie-Solomon encoder uses a convolutional code that is used for the contraction of 8〇2.11a and .llg. Further, because 802.11η will require a longer frame (perhaps 4096 bytes) than .lla (usually 1500 bytes) and a frame error rate requiring farmland to achieve high input and output,

The Lid-Solomon code works well under these conditions. Note that with more complex, higher performance, the Leder-Solomon encoder can be implemented with the higher complexity expected. Comparisons with BER (Bit Err〇r, bit error rate) and FER performance with external Reed-Solomon codes demonstrate that performance limits allow for multiple channels, signal-to-noise ratios, and lower BER. For this example, assuming the processing of the read butterfly, the bit interleaving of the ideal inner code, the bit errors are all self-distributed, and the ideal outer code H and the interlace' use the bit error rate calculated by the merge range. From this point of view, _R<1%) of the current cumulative distribution function (amu hemp D*b face F_tion, CDF) as a sturdy device with 2 jewels 2 33 1305090 can,: _ model δ and D, The singularity of the singularity of the singularity of the singularity of the singularity of the singer of the singer of the singer of the singer The channel encoder 312 _ 岐 个 个 个 个 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = structure.

The sequence includes a wireless communication between one or a plurality of wireless communication devices. The signal frame contains information about the frame length, the data rate in the frame, and so on. In the real money, the preamble part and the 峨 frame pass through the receiver, the track, the tap, and the receiver. The service half _ and: # _ = pass or different the channel encoder, or its part, the receiver's internal period I f response time. For example, the number of bytes and/or the data u box of the job frame can be interleaved based on the size of the interleaver and the external Ryder Solomon code based on the size of the Reed Solomon. Once enough data has been received to the Li 34 1305090: jin, encoder, subsequent byte wanted interleaver and the number of bytes through the interleaver and / or Li De Solomon encoder = speed, signal _ The next time, Li De _ _ _ _ _ _ into the corresponding time of the δ hai receiver.

The longer the depth, the more coding gain, but the increase of if. However, depths of 3 to 5 provide an acceptable compromise for 8G2.un applications, and other depths can be used. m, to Fig. 23' The Lie-Solomon encoder can be a [239, 255] coded two:: receives the input from the switching element S2. Thus, the Lidd Solomon code = also, the flat code is outputted by the interlace H, or the (4) input data. In one embodiment ^—a dragon_recording element_1 often finds most of the m) is sent through the entire queue (that is, the switching element I matches the interleaver to $de_Solomon editor f) De-Solomon encoder, coupled to a perforated convolutional encoder). For the end of the frame, the _ is changed to send these low groups, so that the machine interleaver and / or Li De-Solomon encoder are passed. The pass-through operation allows the receiver to reduce its time, as it is not necessary to have all of the received Wei Liede Solomon decoders. . In fact, it is desirable to decompose the received data into a 239-bit segment of the Liede-Solomon encoder. The remaining 35 1305090 bytes that are not at the end of the frame that are not part of the 239 byte segment are not encoded by the Lie-Solomon code. In order to balance the maximum performance and the smallest anti-scale, input: #6-bit tuple can be decomposed into Rx N byte segments 'where N is the depth of the interleaver, r is the code word of the German encoder the size of. The bytes suitable for these segments will be stolen and the encoder. Multiply the byte under 1J through the system but still be programmed with _239 bytes or shorten the code of the Li Qin Solomon encoder? . Alternatively, the remaining bytes can pass through the interleaver and the Reed-Solomon encoder. μ, the perforated convolutional encoder can be operated to ground to receive from the switching element, such that the perforated convolutional encoder also encodes the Lied-Solomon encoder, or the service half frame and/or Or the encrypted data of the data portion of the frame. In the embodiment, the punctured convolutional encoder may be a polynomial and a state ratio 1/2 code. The encoder can be perforated mode [(10); 1 is called the perforation rate of 3/4; perforated mode [1111; touch] perforation ratio 4/5; perforated mode [iimG; mm] is perforated to a code rate of 5/ 6; and _ called perforation into code (four). Within these perforation modes, one bit represents the bit of the call and one bit represents the bit that is perforated. In another embodiment, the perforated convolutional code material is a 1/2 generation stone horse with a ratio of 256 to G and 7538. The encoder can be perforated into a perforation mode [111; 100] to a code rate of 3/4; perforated mode (10) 4/5; perforated mode___1] perforated to a code rate of 5/6; and by Hi [y〇 1011; 1010100] Piercing into a code rate of 7/8.

The perforation convolutional encoder can be a Viterbi encoder, from the figure 36 1305090 11B The bit-level de-interlace receives a single symbol stream and encodes it to generate internal punctured coded data. In an implementation towel, the punctured convolutional decoder can be a Gg=133 々#1718 64-state ratio 1/2 code.

Corresponding terminology. Such a Lu industry can accept tolerances ranging from less than 1% to 2% and corresponding to, when not limited to 'component impurities, integrated circuit program changes, temperature changes, time Rise and fall and/or thermal noise.

As one of ordinary skill in the art will also recognize that inferred coupling (i.e., one element is coupled to another element by reasoning) includes direct and indirect coupling between the two elements, with "feasible coupling" (operablycoupled)" the same way.
