Fig. 2 is the overall flow figure of the ascending performance method of testing of the multiple antennas mobile terminal of the embodiment of the present invention, and the workflow of the ascending performance test system of the multiple antennas mobile terminal of the present embodiment is described below with reference to Fig. 2.
As in figure 2 it is shown, L road signal is processed by signal grouped element 12, form K bar multipath signal, and be divided into K bar multipath signal after N group multipath signal exporting (step S1).
Specifically, L road signal, according to channel model, is carried out multipath channel process, forms K bar multipath signal by the signal packet subelement 121 in signal grouped element 12.In the present embodiment, every multipath signal is preferably and is obtained by 10 strip footpath signal syntheses, carrys out analogue signal from the space-multipath fading profiles before multiple antennas terminal to base station simulator antenna to be measured with this.
Passage configuration control unit 123 is according to the exploring antenna in full noise elimination darkroom and positional information, it is determined that multipath signal rule of classification.
It should be noted that, in the present embodiment, the general configuration in full noise elimination darkroom is as follows: exploring antenna number is generally 24,32,64, and all horizontal homogeneous is distributed in terminal surrounding to be measured, and exploring antenna number represents the angle simulation precision that full noise elimination darkroom can reach.By sending the signal of different capacity in different time, locus, the multi-path information such as time delay in simulating multi-path environment, angle of arrival, PAS.
Determined multipath signal rule of classification is: the angle that arrives of every multipath signal is normalized to the integral multiple arriving angular unit angle value closest to this multipath signal, then the multipath signal with identical normalization arrival angle value is divided into one group.Wherein, unit angle value refers to the angle in full noise elimination darkroom between any two exploring antennas.
It is configured to example: angle simulation step-length S=(360 °/24)=15 ° with 24 exploring antennas, determine that group technology is according to unit angle value S: the arrival angle value of every multipath signal is defined as the integral multiple (0 ° of arrive angle actual value closest to every multipath signal 15 °, ± 15 °, ± 30 °, ... ± 180 °), then the multipath signal with identical arrival angle value being classified as one group, often in group, the angle that arrives of all multipath signals is the integral multiple of 15 °.
It addition, according to the line of exploring antenna and terminal to be measured in the plane that exploring antenna is constituted relative to the angle (AOA value) of reference line to every antenna number An, n ∈ [-11 ,+12], reference line is taken as the line of A0 and A12, referring to Fig. 3.
After again, signal connexon unit 122 is according to multipath signal rule of classification, the K bar multipath signal of reception is divided into N group multipath signal, and exports to exploring antenna allocation units 13 through the output port of signal grouped element 12, record the arrival angle value of multipath signal on each output port simultaneously.
Channel model for SCM, ITU-RM.2135, WINNERII definition, the number wherein comprising main footpath is generally 10-20, and the output port number of channel packet unit 12 is generally less than 10, so needing multipath signal to be grouped with certain rule, such that it is able to the output port of multiplexed signals grouped element 12, guarantee that, under the premise not increasing signal grouped element number, multi-path information can be delivered on exploring antenna.Wherein, N is equal to the actual signal grouped element 12 output port number enabled.
K bar multipath signal is grouped, solves multipath number and the signal grouped element 12 unmatched problem of output port number, both remained the angle information of multipath signal, and solved again the problem that channel simulator grouped element 12 output port number is limited.
Wherein, multipath signal rule of classification is: the angle that arrives of every multipath signal is normalized to the integral multiple arriving angular unit angle value closest to this multipath signal, then, the multipath signal with identical normalization arrival angle value is divided into one group, wherein, unit angle value refers to the angle in full noise elimination darkroom between any two exploring antennas.For example, if exploring antenna number is 24, then the unit angle value of its correspondence is 15 °.
It follows that exploring antenna allocation units 13 are according to the quantity of exploring antenna in full noise elimination darkroom and positional information, the N group multipath signal of input is distributed to corresponding exploring antenna (step S2).Specifically, quantity and the positional information of the exploring antenna in full noise elimination darkroom are stored by full noise elimination darkroom configuration control unit 131.The allocation rule of exploring antenna determined by exploring antenna distribution subelement 132.The exploring antenna connexon unit 133 allocation rule according to exploring antenna, arrives the N group multipath signal of input in angle value by it and is attached with exploring antenna, complete the distribution to respective angles exploring antenna of the N group multipath signal.
Wherein, the allocation rule of exploring antenna is: the angle information being grouped according to each output port multipath of signal grouped element 12, is attached by the exploring antenna often organizing the corresponding angle of multipath signal.Wherein, the angle of exploring antenna refer to the line of this exploring antenna and base station simulator in the plane that exploring antenna is constituted relative to the angle of reference line.Reference line is a diameter in the circumference that exploring antenna is constituted, it is preferred to horizontal diameter.It should be noted that herein with respect to line preferred levels diameter, meet general custom, it is simple to understand and calculate.
Finally, test cell 14 by N group multipath signal by exploring antenna be sent to base station simulator (base station simulator essence is a signal processor, under the test environment simulation actual communication in base station.), and carry out to the received signal processing and measuring by base station simulator, obtain the up emitting performance (step S3) of multiple antennas terminal to be measured 11.Base station simulator receives after the signal of multi-antenna terminal, measures parameters such as obtaining N group multipath signal arrival angle, time delay, power.The up emitting performance of multi-antenna terminal is calculated afterwards according to measurement result.Additionally, it should be noted that, here up emitting performance refers generally to: total radiant power (TotalRadiatedPower, TRP), by receiving the time delay of multipath signal, arrive angle, power and process and calculate the radio-frequency radiation performance finally giving terminal.
In sum, the ascending performance test system of the multiple antennas mobile terminal that the embodiment of the present invention provides, on the basis based on full noise elimination darkroom, by multipath signal is carried out packet transaction, such that it is able to the output port of multiplexed signals grouped element, reduce the cost increasing number of devices because of device port number not.And, by the multipath signal after packet being carried out the distribution of dynamic exploring antenna resource, reappear real wireless multi-path communication environments.It addition, multiple antennas mobile terminal to be sent by base station simulator reception process and the measurement of signal, obtain the Devices to test up emitting performance under multiple antennas scene.
