| Abstract(in English) | This paper presents field experimental results of the coherent multistage interference canceller(COMSIC) with decision-feedback channel estimation in the transmission-power-controlled W-CDMA reverse link. Experimental results elucidate that when a high-rate user with high transmit power moves at the average speed of approximately 30 km/h along with a low-rate desired user, the block error rate(BLER) of the COMSIC output improves most when the averanging interval of the SIR measurement needed for fast TPC is approximately 20 msec since the interference of the desired user fluctuates due to fading. Furthermore, we clarify that with the optimized SIR measurement interval of fast TPC, the required transmit power of a mobile station employing COMSIC with decision-feedback channel estimation is decreased by approximately 2.0 dB compared to that when using matched-filter-based Rake receiver at the ratio of the target E_b/I_0 of the desired user to interfering user, ΔE_b/I_0=-6dB. |
