Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and system of testing the wireless terminal combined detection performance.
Background technology
In CDMA (Code-Division Multiple Access, code division multiple access) mobile communication system, each subscriber signal superposes on time domain and frequency domain, needs to use a kind of method that each subscriber signal is separated.Joint-detection (Joint Detection) technology is that the multiple user signals that generally is used in cdma system, particularly 3-G (Generation Three mobile communication system) TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess, the TD SDMA) system detects and the technology of separating.It makes full use of multiple access and disturbs (Multiple Access Interference), uses the channel estimation value of training sequence (Midamble), handles the signal of a plurality of code channels simultaneously, thereby demodulates user data.
As shown in Figure 1, be downlink combined measuring ability schematic diagram.D wherein
kRepresent k user's data vector, c
kThe multi-user that spreading code and the scrambler of representing k user, e are represented to superpose together launches data, and e ' expression stack multi-user together receives data, n representation space white noise, h '
kThe channel impulse response of representing k user, b '
kThe compound channel impulse response of representing k user, d '
kRepresent that k user is through the data estimation value after the joint-detection.TCP
kBe k user's code channel transmitting power, ISCP is for disturbing and noise power (Interference Signal Code Power) RSCP
kBe k user's code channel received power (Received Signal Code Power), SNR
kIt is k user's signal to noise ratio (Signal Noise Ratio).
Wireless terminal use associated detection technique can reduce the interference from other users, thereby has improved the demodulation performance of terminal, has reduced the transmitting power of base station, has improved the coverage of base station.
Tradition joint-detection method of testing is by measuring and competitive list user's Interference Signal Code Power ISCP and multi-user's ISCP, and the qualitative joint-detection of considering gains.Concrete grammar is as follows:
1. a sub-district selecting the TD-SCDMA system that terminal can normally insert is as test cell;
2. in test cell, behind the starting up of terminal, initiate an AMR 12.2K audio call, specify the uplink and downlink time slot during access, suppose and insert ascending time slot 2, descending time slot 5; Base station side uses trace tool to obtain to insert user's ISCP, carries out statistical average, obtains the ISCP under single user's condition
Single user
3. use the N TD-SCDMA of portion terminal to initiate N AMR 12.2K audio call and maintenance at the same ascending time slot and the same descending time slot of this test cell; After waiting for the stable maintenance of N user, obtain N the ISCP under the user situation in base station side, and carry out statistical average, obtain the ISCP under multi-user's condition
The multi-user
4. compare ISCP
Single userAnd ISCP
The multi-user, the gain of qualitative analysis joint-detection.
If ISCP
Single userAnd ISCP
The multi-userBe more or less the same, as differ 1-2dB, then show not because insert more users to cause disturbing rapid increase, can qualitatively know the joint-detection gain.
A kind of Apparatus and method for of description joint-detection effect that can be quantitative is provided in the prior art.This equipment comprises control unit, data analysis unit and analytic unit, and control unit wherein is used to control the terminal access test cell of predetermined number, keep the scheduled time, and informing base station is measured parameter current; Data analysis unit is used to store the parameter of base station measurement; Analytic unit is used for obtaining the joint-detection gain factor according to calculation of parameter.Concrete grammar is as follows:
1. select sub-district A and sub-district B as test cell, sub-district A and sub-district B are each other with adjacent sub-district frequently;
2. M+N starting up of terminal of control unit control inserts sub-district A, initiates M+N AMR 12.2K audio call, specifies the uplink and downlink time slot during access, supposes and inserts ascending time slot 2, descending time slot 5;
3. data analysis unit obtains to insert user's RSCP from base station side

M survey+N originally, SNR
M Survey+N originally
4. N TD-SCDMA terminal switched to sub-district B, switch the back and specify the uplink and downlink time slot, suppose and insert ascending time slot 2, descending time slot 5;
5. data analysis unit obtains to insert user's RSCP from base station side
Outside the M survey+N, ISCP
Outside the M survey+N, SNR
M Outside the survey+N
6. the joint-detection gain factor can be expressed as:
The employed data of joint-detection all are to obtain from base station side in the above-mentioned joint detection process, and what this joint-detection testing scheme was primarily aimed at is the base station, do not relate to the test to the joint-detection gain of terminal.The TD-SCDMA base station system can easily obtain each user profile of this base station in the prior art, as code channel configuration, Midamble configuration etc., carry out joint-detection according to the information that obtains, terminal then can't obtain these information from signaling, and that these information are associated detection techniques is necessary, can adopt associated detection technique so it has been generally acknowledged that the TD-SCDMA base station, and terminal can adopt other receiver technology.And in fact, the TD-SCDMA terminal can be by channel estimating and other hypothesis, estimate other users' information, code channel as other users disposes, Midamble disposes etc., terminal just can utilize this user profile and other user profile that estimate to carry out joint-detection like this, and this technology can be called the joint-detection blind Detecting.
But, the scheme of the joint-detection blind Detecting of the employed terminal of different terminals manufacturer has nothing in common with each other in the prior art, cause the difference on effect of joint-detection blind Detecting of terminal bigger, and be still blank for the testing scheme of the effect of the joint-detection blind Detecting of terminal.
