Abstract :
The performance of combined FEC/ARQ techniques for a direct-sequence CDMA system using coherent binary phase shift keying (BPSK) modulation is investigated. Throughput and delay are analyzed for the cases of slow and fast fading, considering the application of maximal ratio combining in light and heavy shadowing environments. By calculating the packet success probability, numerical results are presented for the throughput and delay. FEC with selective-repeat ARQ is implemented using BCH codes of varying lengths
