1, g
2..., g
N, g
1＜g
2＜...＜g
N, can make receiver sensitivity satisfy the static sensitivity index request by adjusting the rf gain rank.
For example, receiver static sensitivity index request is [P
Min(dBm), P
Max(dBm)], rf gain g
1The corresponding range of sensitivity is [P
2(dBm), P
Max(dBm)], rf gain g
2The corresponding range of sensitivity is [P
Min(dBm), P
1And P (dBm)],
2≤ P
1, then we rf gain can be set at 2 grades adjustable, by adjusting gain g
1And g
2Just can make sensitivity satisfy index request.
Step S602, according to the multiplexing method of receiver to the PS service wireless resource, the channel compound mode, the setting total block data is M, sets can to hold number of users K at most, and be M piece setting initial user number, for F user is provided with initial AGC value.
Figure 1 shows that the professional PDCH multi-frame structure of PS, form that wherein comprised 12 pieces again, each piece is made up of 4 continuous tdma frames by 52 tdma frames.In addition, the tdma frame that also has two idle frames and two Timing Advance control channels that are used to divide into groups (Packet Timing advanced Control channel abbreviates PTCCH as).Consider the composite type of PS business, PDTCH channel maximum available block number in 52 multi-frame structures is 12.Set M=A*B*C, A is a carrier number, and B is every carrier wave timeslot number, and gsm system is 8, and C is every time slot largest block number, is 12 here, and each independent channel is provided with inactive users number respectively.
At the PS business, set and to hold number of users K=A*D at most, wherein, A is a carrier number, D is that every carrier wave can hold the PS number of users at most, and in gsm system, D is 64 (temporary up-link block flow (Temporary Block Flow, abbreviate TBF as) maximum 32, maximum 32 of descending TBF considers limiting case, promptly, single up and all occupied words of single downlink TBF, number of users is 64).For each user is provided with initial yield value (that is initial AGC value) respectively.
Initial yield value should be set according to the application scenarios of base station, if outdoor cover type macro base station should be set to higher rf gain value; If the little base station of indoor cover type should be set to lower rf gain value.
Step S603, the PCU unit is according to the allocation strategy of up resource of PS business, determine the corresponding relation between piece Mi and the user Kj, and it is passed to Base Band Unit, Base Band Unit is according to the corresponding relation that receives, set up the mapping table of piece M and user K, put user's effective marker, and the real-time update mapping table.
When travelling carriage or service universal packet wireless business affair support node (Serving General packet radio service support node abbreviates SGSN as) initiation PS business, PCU sets up the unit user Kj.If the PCU unit distributes up resource for this user, then the PCU unit will shift to an earlier date the user number Kj of up number Mi that will distribute and correspondence will be passed to Base Band Unit.Base Band Unit is set up the mapping table of piece M and user K after receiving this corresponding relation, put user's effective marker of the user number Kj of piece Mi correspondence, and according to receiving new this mapping table of corresponding relation real-time update.
Step S604, after operation of receiver is normal, calculate corresponding antenna opening received signal power in base band at each time slot, obtain current piece Mi according to timing control unit, tabling look-up obtains corresponding user Kj, obtains the AGC value of the current configuration of user Kj, in conjunction with the AGC value of the current configuration of user Kj, calculate the new AGC value of this user Kj, and user's effective marker of the user Kj of clear piece Mi correspondence.
At first, the calculated signals baseband signal power average value that receives according to the current time slots base band, then, and the baseband signal power average value that obtains according to the radio frequency fixed error corrected Calculation that causes by each AGC value, thus the antenna opening received signal power obtained.
For preventing that AGC from adjusting shakes, just in design, should adopt continuous a plurality of TDMA received signal to cross the mechanism of adjusting the AGC value behind the adjustment thresholding.On the other hand, in order not influence regular traffic, the adjustment time is unsuitable long.Consider that blocks of data is to be made of 4 continuous tdma frames, can adopt the adjustment time in the design is 4 tdma frame times,, after continuous 4 TDMA received signals are crossed the adjustment thresholding, just adjusts AGC that is.Describe adjustment process below in detail:
At first, obtain piece Mi according to current receiving slot, channel composite type, frame number processing, tabling look-up obtains the user number Kj of piece M i correspondence, if the user is the disabled user, need not adjust directly and return, otherwise, obtain the current AGC of this user, continue following process;
The antenna opening received signal power that previous step is obtained carries out the recurrence average treatment, obtains the received signal power average value P
Avg=(1-α) * P
Old+ α * P
New, wherein, P
AvgBe received signal power mean value, P
OldBe received signal power before, P
NewBe new received signal power;
If the AGC Configuration Values is g
2, then following processing:
If received signal level is greater than threshold value P1, then g
1Counter begins counting, g
2Counter O reset;
If received signal level is less than threshold value P 1, then all zero clearings of Counter Value;
If g
1Counter Value arrives thresholding (thresholding is 4), and the AGC value of user Kj correspondence is updated to g
1, clear two Counter Values.
If the AGC Configuration Values is g
1, then following processing:
If received signal level is less than threshold value P2, then g
2Counter begins counting, g
1Counter O reset;
If received signal level is greater than threshold value P2, then two all zero clearings of Counter Value;
If g
2Counter Value arrives thresholding, and the AGC value of user Kj correspondence is updated to g
2, clear two Counter Values;
User's effective marker of the user Kj of clear piece Mi correspondence.
Step S605, if arrive the AGC configuration constantly, the AGC value that then previous step is obtained is configured in the radio frequency amplifier by feedback control unit, otherwise, continue to wait for that the AGC configuration arrives constantly.
The AGC configuration needs choose reasonable constantly, if configuration can influence the data of a time slot constantly too early, can influence the data of this time slot if spend evening.If the AGC configuration arrives constantly, then obtain current piece Mi according to timing control unit, tabling look-up obtains corresponding user Kj, does not need configuration if the user is invalid, the AGC value of the user Kj that previous step is calculated if the user is effective is configured in the radio frequency amplifier by feedback control unit.
Step S606, if the PS business does not finish, repeating step S603, step S604 and step S605; If the PS service ending, then the PCU unit discharges user Kj, no longer transmits user profile to Base Band Unit, and Base Band Unit stops the automatic gain control flow of PS business.
In sum, adopt the present invention, improved PS performance of services and stability, make that the AGC adjustment between a plurality of users is separate, can not influence each other, thereby guaranteed the normal operation of a plurality of user PS business.
