Abstract
Undersea acoustic links are highly complex due to the various propagation effects like the spreading, multipath, intersymbol interference, fading, etc.. Orthogonal frequency division multiplexing is found to be a good choice to combat intersymbol interference. It enables simpler equalization as well. Coding can be used in conjunction with OFDM to achieve error correction, improved security as well as privacy. The process of coding when combined with interleaving helps to improve the error rate performance of an OFDM system significantly. This paper investigates the performance of a BCH coded BPSK based OFDM system with and without interleaving. The simulated system performance has been compared for different BCH codes.
