Abstract :
We analyze the performance improvement of the SFH-CDMA/FSK signal with truncated type-II hybrid ARQ and MRC diversity techniques in mobile communication channel which is characterized by AWGN, MUI (multiuser interference), and Nakagami fading. Using the derived equations, the error probability and the throughput are evaluated and shown in figures. The most important results that we have obtained are that the truncated type-II hybrid ARQ scheme provides more efficient improvement over an FEC (forward error correction) scheme and the amount of improvement is increased when it is combined with MRC diversity technique. Therefore, it is proper for mobile and radio data communication systems that require high reliability and delay-limited applications
