Fig. 1 is the functional block diagram after the wireless communication system 100 of the present invention one first embodiment is simplified.Wireless communication system 100 includes radio communication circuit 110, commutation circuit 120, antenna sets 130 and antenna sets 140, and wherein, radio communication circuit 110 includes transmission circuit (transceiver) 112, control module 114 and storage medium 116.
On the implementation, the transmission circuit 112 in the radio communication circuit 110, control module 114 and storage medium 116 can be incorporated in the single circuit chip.In certain embodiments, also radio communication circuit 110 and commutation circuit 120 can be integrated into the single circuit chip.In addition, the needs depending on the circuit running all can include respectively one or more antennas in antenna sets 130 and the antenna sets 140.Comprise among the embodiment of many antennas in antenna sets, antenna sets can be connected with commutation circuit 120 by bus, and also can be connected by bus between commutation circuit 120 and the transmission circuit 112.
In the storage medium 116 of radio communication circuit 110, store to control the computer program of antenna diversity (antenna diversity) running of wireless communication system 100, for example firmware program (firmware).Control module 114 is coupled to transmission circuit 112 and storage medium 116, and the computer program that can carry out in the storage medium 116 is carried out the antenna diversity running with control wireless communication system 100.The Fig. 2 that below will arrange in pairs or groups further specifies the function mode of wireless communication system 100 to Fig. 3.
Sequential chart after the embodiment that Fig. 2 and Fig. 3 operate for the antenna diversity of describing wireless communication system 100 simplifies.The control module 114 of radio communication circuit 110 can be divided into a plurality of periodic operation time period, for example the operation time period P0 shown in Fig. 2 and Fig. 3, P1 and P2 with the running of wireless communication system 100.In the present embodiment, include again test period and normal operation period in each operation time period.For example, operation time period P0 comprises test period T0 and normal operation period N0; Operation time period P1 comprises test period T1 and normal operation period N1; Operation time period P2 then comprises test period T2 and normal operation period N2.
On the implementation, control module 114 can be arranged to the length of all operations period identical, also can optionally some operation time period be prolonged or shorten.In addition, control module 114 can be arranged to the test period in each operation time period to join with the normal operation period, and the interval period of suitable length also can be set between the two.
In each test period, control module 114 can arrange (configure) commutation circuits 120 and transmission circuit 112 is switched to antenna sets 130 and stay for some time, and then again transmission circuit 112 is switched to antenna sets 140 and stays for some time.When transmission circuit 112 switched to antenna sets 130, transmission circuit 112 can come receiving and transmitting signal by antenna sets 130, and 114 of control modules can record the package transmission amount (throughput) of antenna sets 130 during this section.When transmission circuit 112 switched to antenna sets 140, transmission circuit 112 just can come receiving and transmitting signal by antenna sets 140, and control module 114 then can record the package transmission amount of antenna sets 140 during this section.
In other words, control module 114 can record antenna sets 130 and the package transmission amount of antenna sets 140 in each test period, with the foundation alternatively in the antenna sets that will use in the follow-up normal operation period.In this package transmission amount of censuring, it can be the data volume (for example figure place or package number) of specific group of antennas all packages that institute receives and/or transmits in each test period, it also can be the data volume of this antenna sets all packages of within the unit interval, transmitting and/or receive, its unit can be bits per second (bit per second, bps) or per second package number (packet per second, pps).When calculating the package transmission amount, control module 114 also can only will be addressed to (addressing to) package of wireless communication system 100 includes the calculating of package transmission amount in.For example, control module 114 can be only be the calculating that the package that points to wireless communication system 100 is included the package transmission amount in the destination-address in the package (destination address, DA) or receiver address (receive address, RA).
Perhaps, control module 114 also can only be included the package of specific coding type in the calculating of package transmission amount, to reduce required operand.For example, control module 114 can only record the data volume (for example figure place or package number) of specific group of antennas package of institute's specific coding type of receiving and/or transmitting in each test period, or the data volume of the package of this antenna sets specific coding type of transmitting and/or receive within the unit interval.In one embodiment, the package of aforesaid specific coding type refers to adopt the package of the encoding scheme of encoding scheme (modulation and coding scheme, MCS) more than 8.
In addition, control module 114 also can be ignored the package of some special purpose such as broadcasting packages (broadcast packet), control package (control packet) or management package (managementpacket) when calculating the package transmission amount.
In addition, in each test period, control module 114 also can be arranged to transmission circuit 112 and the time span that couples of different antennae group unequal.If control module 114 arranges commutation circuit 120 and after a fc-specific test FC period transmission circuit 112 switched to antenna sets 130, representative antennas group 130 collection of letters quality at that time is better than antenna sets 140.Generally speaking, the collection of letters quality of antenna sets 130 in the next one test period also probably understood ratio antenna group 140 and must be got well.Therefore, control module 114 just can be arranged to transmission circuit 112 and the time span that couples of antenna sets 130 greater than the couple time span of transmission circuit 112 with antenna sets 140 in the test period at the next one.
For example, suppose that control module 114 arranges commutation circuit 120 and after test period T0 transmission circuit 112 switched to antenna sets 130, then in next one test period T1, commutation circuit 120 can be set transmission circuit 112 is switched to 130 1 very first times of antenna sets, then again transmission circuit 112 is switched to the 140 one the second times of antenna sets, and length that should the very first time is arranged to the length greater than this second time.
Thus, because transmission circuit 112 shortened in the time that test is coupled to the antenna sets that the collection of letters may be relatively poor in the period, can reduce the harmful effect that the switching of antenna sets may cause the data transmission efficiency (for example package transmission amount or message transmission rate) of wireless communication system 100.
Perhaps, control module 114 also can each test arrange in the period commutation circuit 120 with transmission circuit more than 112 time antenna sets 130 and 140 staggered switchings of antenna sets, to shorten the time that couples of transmission circuit 112 each and antenna sets that may be relatively poor of collecting mail in the test period.The harmful effect that the switching that such mode can reduce antenna sets equally may cause the data transmission efficiency of wireless communication system 100.
In one embodiment, control module 114 not only can each test arrange in the period commutation circuit 120 with transmission circuit more than 112 time antenna sets 130 and 140 staggered switchings of antenna sets, also can be arranged to not identical with the time span that couples of different antennae group transmission circuit 112 at every turn.For example, in the embodiment of Fig. 2, control module 114 can cut into test period T1 8 inferior period T11～T18, and wherein, the length of inferior period T11, T13, T15, T17 is respectively less than the length of inferior period T12, T14, T16, T18.Suppose that control module 114 arranges commutation circuit 120 transmission circuit 112 is switched to antenna sets 140 in normal operation period N0, then control module 114 can arrange commutation circuit 120 in the inferior period T11 that tests period T1, T13, T15, T17, transmission circuit 112 is switched to antenna sets 130, and in inferior period T12, T14, T16, T18, transmission circuit 112 is switched to antenna sets 140.
After if control module 114 test period T1 finish, determine that control commutation circuit 120 switches to antenna sets 130 with transmission circuit 112, then control module 114 can be tested the next one period T2 and be cut into period T21～T28 8 times, the length of time period T21, T23, T25, T27 wherein is respectively greater than the length of inferior period T22, T24, T26, T28.Control module 114 can arrange commutation circuit 120 in the inferior period T21 that tests period T2, T23, T25, T27, transmission circuit 112 is switched to antenna sets 130, and in inferior period T22, T24, T26, T28, transmission circuit 112 is switched to antenna sets 140.
Such mode has further shortened each time that couples with the antenna sets that may be relatively poor of collecting mail of transmission circuit 112, the harmful effect that the switching that more can reduce antenna sets may cause the data transmission efficiency of wireless communication system 100.
In one embodiment, control module 114 can be arranged to the length of each normal operation period respectively to test 10～100 times of period, and in each test period, control module 114 can be each with transmission circuit 112 and time that couples of the better antenna sets of collecting mail, be arranged to 4～9 times of each time that couples with the relatively poor antenna sets of collecting mail of transmission circuit 112, to improve the overall data transmission usefulness of wireless communication system 100.
In wireless communication system 100, the control module 114 of radio communication circuit 110 can the indivedual package transmission amounts in the single test period be added up antenna sets 130 and antenna sets 140, or the indivedual package transmission amounts in a plurality of test period are added up to antenna sets 130 and antenna sets 140, and according to resulting package transmission amount statistical value (throughput statistics) commutation circuit 120 ensuing runnings are set.At this package transmission amount statistical value of censuring, can directly use the package transmission amount of specific group of antennas in the single test period, or the time average (time average) of the package transmission amount of this specific group of antennas in the single test period, also can be summation, mean value, time average (timeaverage), mobile and (moving sum) or moving average (moving average) etc. of the package transmission amount of specific group of antennas in a plurality of test period.
For example, control module 114 can be when a target detection period (for example aforesaid T0, T1 or T2) finishes, comparison antenna sets 130 and antenna sets 140 are corresponding to the package transmission amount statistical value of this target detection period, and foundation result relatively arranges commutation circuit 120.In one embodiment, if the package transmission amount statistical value of antenna sets 130 greater than the package transmission amount statistical value of antenna sets 140, control module 114 can judge that antenna sets 130 transmission usefulness at that time is better.Therefore, control module 114 can arrange commutation circuit 120 and after the period, transmission circuit 112 be switched to antenna sets 130 at this target detection, so that transmission circuit 112 can come receiving and transmitting signal by antenna sets 130 in the ensuing normal operation period.Otherwise, if the package transmission amount statistical value of antenna sets 130 less than the package transmission amount statistical value of antenna sets 140, with transmission circuit 112 switches to antenna sets 140 at this target detection after the period just control module 114 can arrange commutation circuit 120.
Perhaps, control module 114 can be when a target detection period finishes, relatively antenna sets 130 and antenna sets 140 be corresponding to comprising the package transmission amount statistical values of this target detection period in interior a plurality of test period, and according to result relatively commutation circuit 120 is set.For example, control module 114 can be when target detection period T2 finishes, with antenna sets 130 corresponding to test period T0, T1, and the package transmission amount statistical value of T2 and antenna sets 140 corresponding to test period T0, T1, and the package transmission amount statistical value of T2 compare, with the foundation of the antenna sets that will in ensuing normal operation period N2, use as selection.In one embodiment, if the package transmission amount statistical value of antenna sets 130 greater than the package transmission amount statistical value of antenna sets 140, control module 114 can judge that antenna sets 130 transmission usefulness at that time is better.Therefore, control module 114 can arrange commutation circuit 120 after this target detection period T2, and transmission circuit 112 is switched to antenna sets 130, so that transmission circuit 112 can come receiving and transmitting signal by antenna sets 130 in ensuing normal operation period N2.Otherwise, if the package transmission amount statistical value of antenna sets 130 less than the package transmission amount statistical value of antenna sets 140, switches to antenna sets 140 with transmission circuit 112 just control module 114 can arrange commutation circuit 120 after this target detection period T2.The benefit that adopts this mode is to increase sample time, reduces the possibility that causes erroneous judgement because of the acute variation of instantaneous package transmission amount.On the implementation, control module 114 also can the basis signal status transmission dynamically adjust will foundation the number of test period.
In another embodiment, control module 114 can when a target detection period (for example T2) finishes, utilize the mode of aforementioned arbitrary embodiment to select first tentative (tentative) antenna sets.Then, control module 114 will be fixed tentatively antenna sets and the final antenna selection result of previous several test period (for example T0 and T1) again and be carried out most decision (majority rule) and judge.If the result of the most decision number of times that to be antenna sets 130 selected is greater than the selected number of times of antenna sets 140, control module 114 can arrange commutation circuit 120 at this target detection after the period, transmission circuit 112 transmission circuit 112 switched to antenna sets 130, so that can come receiving and transmitting signal by antenna sets 130 in the ensuing normal operation period.Otherwise, if the selected number of times of antenna sets 130 with transmission circuit 112 switches to antenna sets 140 at this target detection after the period just control module 114 can arrange commutation circuit 120 less than the selected number of times of antenna sets 140.This practice can increase sample time equally, reduces the possibility that causes erroneous judgement because of the acute variation of instantaneous package transmission amount.
By above stated specification as can be known, aforesaid control module 114 can dynamically be adjusted transmission circuit 112 employed antenna sets according to wireless communication system 100 residing environment, can significantly improve the antenna collection of letters quality of antenna sets 130 and antenna sets 140, and promote thus the transmission speed of wireless communication system 100.
In the foregoing embodiments, package transmission amount and the package transmission amount statistical value of respective antenna group in each test period is to be calculated by the control module 114 of radio communication circuit 110.But this is part embodiment, but not limits to actual execution mode of the present invention.For example, the functional block diagram after Fig. 4 wireless communication system 400 of showing the present invention one second embodiment is simplified.In wireless communication system 400, the packet data after control module 114 can be processed transmission circuit 112 sends processing module 450 to.Processing module 450 can be calculated package transmission amount and the package transmission amount statistical value of respective antenna group in each test period, and result of calculation is returned to control module 114, so that control module 114 is carried out aforesaid antenna sets handover decisions according to this.
On the implementation, processing module 450 can be the central processing unit in desktop PC, mobile computer, flat computer, PDA, mobile phone, audio and video player (for example blue-ray DVD player) or the radio base station, or the computer program of carrying out at these equipment.Also namely, processing module 450 can realize with hardware mode, also can realize with software mode.Be integrated among the embodiment of USB wireless network card (USBdongle) kenel in radio communication circuit 110, commutation circuit 120, antenna sets 130 and antenna sets 140, adopt the framework of Fig. 4 can significantly reduce the required operand of control module 114, and improve simultaneously the antenna collection of letters quality of this USB wireless network card, and effectively promote the transmission speed of wireless communication system 400.
In addition, aforesaid antenna diversity mechanism also can be expanded to the application of using more antenna sets.Below will arrange in pairs or groups Fig. 5 and Fig. 6 is described further.
Fig. 5 is the functional block diagram after the wireless communication system 500 of the present invention 1 the 3rd embodiment is simplified.Fig. 6 is the functional block diagram after the wireless communication system 600 of the present invention 1 the 4th embodiment is simplified.Compared to aforesaid wireless communication system 400, increased by a cover antenna sets 550 in the wireless communication system 500 more.In wireless communication system 500, the transmission circuit 112 of radio communication circuit 110 can receive signal with two cover antenna sets simultaneously.Transmission circuit 112 can merge by the signal that two antenna sets are received, with further lifting signal collection of letters quality.Antenna sets 550 is transmission circuit 112 default wherein cover antenna sets of using.114 of the control modules of radio communication circuit 110 can according to the mode of previous embodiment, be selected one of them next and antenna sets 550 collocation of antenna sets 130 and antenna sets 140.
