Performance analysis for serially concatenated FEC in IEEE802.16a over wireless channels

Abstract

To design an IEEE802.16a wireless transmission system, we investigate the performance of its serially concatenated forward error correction (FEC) system for both additive white Gaussian noise (AWGN) channel and the fully interleaved Rayleigh fading channel (FI-RFC). We derive the union upper bounds on the bit error rate (BER) for the Reed-Solomon (RS) code and the rate-compatible punctured convolutional codes (RCPC). These theoretical bounds are compared with the simulation results and it shows that the derived bounds are fairly tight. In addition, simulation results of the packet error rate (PER) are also presented. We thus in this paper provide researchers a suitable operational range of IEEE802.16a in terms of signal-to-noise ratio and acceptable performance.
