Abstract

In underwater shallow acoustic communication (UWSAC) channel, due to the reflections from bottom and surface, multiple paths propagated resulting Inter Symbol Interference (ISI). In this paper we present the bit error performance of convolution coded orthogonal frequency division multiplexing (CCOFDM) UWSAC system with the implementation of adaptive equalization to minimize the ISI over AWGN and Rayleigh fading based on Recursive least square (RLS) and Filtered Error Least Mean Squares (FELMS) Algorithms. From the simulation results it is observed that FELMS shown to improve BER as compared to an RLS with CCOFDM system..
