Abstract(in English) | This paper experimentally evaluated the bit error rate(BER) performance of single-carrier broadband DS-CDMA(B-CDMA)access scheme using a 100 MHz bandwidth applying SIR measurement-based fast transmission power control(TPC) by laboratory experiments using a multipath fading simulator. The achievable information bit rate is 20.36(2.5)Mbps when the spreading factor is SF=4(32). Experimental results demonstrated that by applying fast TPC, the required average transmit E_b / N_0 at the average BER of 10^<16> with antenna diversity can be reduced by approximately 7 dB compared to that in the case without fast TPC. It was also shown that the average BER of 10^<-6> of 20.36(2.5)Mbps transmission was achieved at the average transmit E_b / N_0 of approximately 6.7(5.0)dB with antenna diversity when L=2 and f_D=20 Hz. Moreover, 2.5 Mbps transmission with average BER below 10^<-6> can be achieved with antenna diversity in multipath fading channels up to 12 paths, which indicates that the Rake path diversity and fast TPC effectively works in a broadband propagation channels. |
