| Abstract(in English) | This paper presents the laboratory experimental results of coherent multistage interference canceller using interference rejection weight control (IRWC) for DS-CDMA mobile radio. From the experimental results, we verified the following results: (1) The effect of the IRWC in laboratory experiments is smaller than that in computer simulation results due to the pathes detection error of Rake combining and to the quantization error of the received signal. (2) When the rejection weights α=0.7, the transmit power of MS is reduced by about 0.5dB compared to the case with a=1.0 without fast TPC, however the effect of IRWC is negligible with fast TPC. (3) There is no obvious performance difference when the number of interfering users increases. (4) When the received power of interfering user is large, no effect of IRWC was observed. (5) It is preferable that small weight a such as 0.7 is used only for the first stage. |
