Fig. 1 is the functional block diagram after the wireless communication system 100 of the present invention one first embodiment simplifies.Wireless communication system 100 includes radio communication circuit 110, commutation circuit 120, antenna sets 130 and antenna sets 140, wherein, radio communication circuit 110 includes transmission circuit (transceiver) 112, control module 114 and storage medium 116.
In implementation, the transmission circuit 112 in radio communication circuit 110, control module 114 and storage medium 116 can be incorporated in single circuit chip.In certain embodiments, also radio communication circuit 110 and commutation circuit 120 can be integrated into single circuit chip.In addition, depending on the needs of circuit running, in antenna sets 130 and antenna sets 140, all one or more antenna can be included respectively.Comprise in 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 with transmission circuit 112.
In the storage medium 116 of radio communication circuit 110, store the computer program that the antenna diversity (antennadiversity) for controlling wireless communication system 100 operates, such as firmware program (firmware).Control module 114 is coupled to transmission circuit 112 and storage medium 116, and the computer program that can perform in storage medium 116 performs antenna diversity running to control wireless communication system 100.Below collocation Fig. 2 to Fig. 3 is further illustrated the function mode of wireless communication system 100.
Fig. 2 and Fig. 3 is the sequential chart after an embodiment of the antenna diversity running describing wireless communication system 100 simplifies.The running of wireless communication system 100 can be divided into multiple periodic operation time period, such as, operation time period P0 shown in Fig. 2 and Fig. 3, P1 and P2 by the control module 114 of radio communication circuit 110.In the present embodiment, test period and normal operation period is included again in each operation time period.Such as, 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.
In implementation, the length of all operations period can be arranged to identical by control module 114, also can optionally some operation time period be extended or shorten.In addition, the test period in each operation time period can be arranged to connect with the normal operation period by control module 114, also can arrange the interval period of suitable length between the two.
In each test period, control module 114 can arrange (configure) commutation circuit 120 and transmission circuit 112 switched to antenna sets 130 and stays for some time, and then again transmission circuit 112 is switched to antenna sets 140 and stays for some time.When transmission circuit 112 switches to antenna sets 130, transmission circuit 112 can carry out receiving and transmitting signal by antenna sets 130, and control module 114 can record the package transmission amount (throughput) of antenna sets 130 during this section.When transmission circuit 112 switches to antenna sets 140, transmission circuit 112 just can carry out 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 the package transmission amount that this censures, it can be the data volume (such as figure place or package number) of specific group of antennas all packages that institute receives and/or transmits in each test period, also can be the data volume of all packages that this antenna sets transmits and/or receives within the unit interval, its unit can be bits per second (bitpersecond, or package number (packetpersecond, pps) per second bps).When calculating package transmission amount, the package being addressed to (addressingto) wireless communication system 100 also only can be included in the calculating of package transmission amount by control module 114.Such as, control module 114 can only by the destination-address (destinationaddress in package, DA) or receiver address (receiveaddress, RA) be point to the calculating that the package of wireless communication system 100 includes package transmission amount in.
Or the package of specific coding type also only can be included in the calculating of package transmission amount by control module 114, to reduce required operand.Such as, control module 114 can the data volume (such as figure place or package number) of only record specific group of antennas package of the specific coding type that institute receives and/or transmits in each test period, or the data volume of the package of specific coding type that this antenna sets transmits and/or receives within the unit interval.In one embodiment, the package of aforesaid specific coding type refers to the package of the encoding scheme adopting encoding scheme (modulationandcodingscheme, MCS) more than 8.
In addition, the package of some special purpose such as broadcasting packages (broadcastpacket), control package (controlpacket) or management package (managementpacket), when calculating package transmission amount, also can be ignored by control module 114.
In addition, in each test period, transmission circuit 112 and the time span that couples of different antennae group also can be arranged to unequal by control module 114.If control module 114 arranges commutation circuit 120, after a fc-specific test FC period, transmission circuit 112 switched to antenna sets 130, representative antennas group 130 collection of letters quality is at that time better than antenna sets 140.Generally, the collection of letters quality of antenna sets 130 in the next one test period also probably can be come good than antenna sets 140.Therefore, control module 114 in the next one test period just can by transmission circuit 112 and antenna sets 130 couple that time span is arranged to be greater than transmission circuit 112 and antenna sets 140 couple time span.
Such as, suppose that control module 114 arranges commutation circuit 120, after test period T0, transmission circuit 112 switched to antenna sets 130, then commutation circuit 120 can be set in next one test period T1 and transmission circuit 112 is switched to antenna sets 130 1 very first time, then again transmission circuit 112 is switched to antenna sets 140 one the second time, and the length of this very first time is arranged to the length being greater than this second time.
Thus, the time being coupled to the antenna sets of collecting mail may be poor due to transmission circuit 112 in the test period shortens, the harmful effect that the data transmission efficiency (such as package transmission amount or message transmission rate) of switching to wireless communication system 100 that can reduce antenna sets may cause.
Or, control module 114 also can arrange commutation circuit 120 and switch staggered between antenna sets 130 and antenna sets 140 for transmission circuit more than 112 time in each test period, with shorten transmission circuit 112 in the test period each antenna sets poor with possibility of collecting mail couple the time.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 arrange commutation circuit 120 and switch staggered between antenna sets 130 and antenna sets 140 for transmission circuit more than 112 time in each test period, also can be arranged to not identical with the time span that couples of different antennae group by transmission circuit 112 at every turn.Such as, in the embodiment of fig. 2, test period T1 can be cut into 8 period T11 ~ T18 by control module 114, wherein, secondary period T11, T13, T15, T17 length, be less than the length of secondary period T12, T14, T16, T18 respectively.Suppose that control module 114 arranges commutation circuit 120 and transmission circuit 112 is switched to antenna sets 140 in normal operation period N0, then control module 114 can arrange the secondary period of commutation circuit 120 at test period T1 in T11, T13, T15, T17, transmission circuit 112 is switched to antenna sets 130, and in secondary period T12, T14, T16, T18, transmission circuit 112 is switched to antenna sets 140.
If control module 114 is tested after period T1 terminates, determine that controlling commutation circuit 120 switches to antenna sets 130 by transmission circuit 112, then the next one can be tested period T2 and cut into 8 period T21 ~ T28 by control module 114, wherein secondary period T21, T23, T25, T27 length, be greater than the length of time period T22, T24, T26, T28 respectively.Control module 114 can arrange the secondary period of commutation circuit 120 at test period T2 in T21, T23, T25, T27, and transmission circuit 112 is switched to antenna sets 130, and in secondary period T22, T24, T26, T28, transmission circuit 112 is switched to antenna sets 140.
Such mode further shorten transmission circuit 112 each with collect mail may be poor antenna sets couple the time, 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, the length of each normal operation period can be arranged to 10 ~ 100 times of each test period by control module 114, and in each test period, control module 114 can couple the time by each for transmission circuit 112 with the preferably antenna sets of collecting mail, be arranged to 4 ~ 9 times of the time that couples of each antenna sets poor with the collection of letters 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 the individual packet transmission amount in the single test period can be added up antenna sets 130 and antenna sets 140, or the individual packet transmission amount in multiple test period is added up to antenna sets 130 and antenna sets 140, and the ensuing running of commutation circuit 120 is set according to the package transmission amount statistical value (throughputstatistics) obtained.At the package transmission amount statistical value that this censures, directly can use the package transmission amount of specific group of antennas in the single test period, or the time average (timeaverage) of the package transmission amount of this specific group of antennas in the single test period, also can be the summation of the package transmission amount of specific group of antennas in multiple test period, mean value, time average (timeaverage), mobile and (movingsum) or moving average (movingaverage) etc.
Such as, control module 114 can at the end of a target detection period (such as aforesaid T0, T1 or T2), relatively antenna sets 130 and antenna sets 140 correspond to the package transmission amount statistical value of this target detection period, and according to the result compared to arrange commutation circuit 120.In one embodiment, if the package transmission amount statistical value of antenna sets 130 is greater than the package transmission amount statistical value of antenna sets 140, control module 114 can judge that antenna sets 130 transmission usefulness is at that time better.Therefore, control module 114 can arrange commutation circuit 120 after this target detection period, and transmission circuit 112 is switched to antenna sets 130, makes transmission circuit 112 can carry out 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 is less than the package transmission amount statistical value of antenna sets 140, control module 114 just can arrange commutation circuit 120, after this target detection period, transmission circuit 112 be switched to antenna sets 140.
Or, control module 114 can at the end of a target detection period, relatively antenna sets 130 and antenna sets 140 are corresponding to the multiple package transmission amount statistical values testing the periods comprising this target detection period, and according to the result compared to arrange commutation circuit 120.Such as, control module 114 can at the end of target detection period T2, the package transmission amount statistical value and the antenna sets 140 that antenna sets 130 are corresponded to test period T0, T1 and T2 compare corresponding to the package transmission amount statistical value testing period T0, T1 and T2, using the foundation of the antenna sets that will use in ensuing normal operation period N2 as selection.In one embodiment, if the package transmission amount statistical value of antenna sets 130 is greater than the package transmission amount statistical value of antenna sets 140, control module 114 can judge that antenna sets 130 transmission usefulness is at that time 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, makes transmission circuit 112 can carry out 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 is less than the package transmission amount statistical value of antenna sets 140, control module 114 just can arrange commutation circuit 120, after this target detection period T2, transmission circuit 112 be switched to antenna sets 140.The benefit of adopting in this way to increase sample time, and the acute variation reduced because of instantaneous package transmission amount causes the possibility of erroneous judgement.In implementation, control module 114 also can basis signal status transmission dynamic conditioning will the number of test period of foundation.
In another embodiment, control module 114 can, at the end of a target detection period (such as T2), utilize the mode of aforementioned any embodiment first to select tentative (tentative) antenna sets.Then, this tentative antenna sets and previous several final antenna selection result of testing the period (such as T0 and T1) are carried out most decision (majorityrule) and are judged by control module 114 again.If the result of most decision is antenna sets 130, selected number of times is greater than the selected number of times of antenna sets 140, control module 114 can arrange commutation circuit 120 after this target detection period, transmission circuit 112 is switched to antenna sets 130, makes transmission circuit 112 can carry out 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 is less than the selected number of times of antenna sets 140, control module 114 just can arrange commutation circuit 120, after this target detection period, transmission circuit 112 be switched to antenna sets 140.This practice can increase sample time equally, and the acute variation reduced because of instantaneous package transmission amount causes the possibility of erroneous judgement.
From aforementioned explanation, the antenna sets that aforesaid control module 114 can use according to the environment dynamic conditioning transmission circuit 112 residing for wireless communication system 100, significantly can improve the antenna collection of letters quality of antenna sets 130 and antenna sets 140, and promote the transmission speed of wireless communication system 100 thus.
