| Abstract(in English) | This paper presents laboratory experimental results on TCP throughput of broadband Orthogonal Frequency and Code Division Multiplexing (OFCDM) wireless access using implemented transceivers in multipath Rayleigh fading channels. In the implemented transceivers, IP packets based on TCP are segmented and mapped into radio packet frame with the length of 0.5 msec, and key techniques such as hybrid ARQ with packet combining, frequency diversity by the 100-MHz broad bandwidth, pilot channel-based coherent detection, Turbo coding, and antenna diversity reception are applied. Experimental results elucidate that the increase of the number of retransmissions bringing about reduced residual radio packet error rate is effective in improving TCP throughput, and that required residual radio packet error rate should be less than 10^<-4> for realizing the TCP throughput with the loss less than 10 % from the throughput of radio packet frame. |
