Studies on undersea acoustic communication links, set up through highly complex and inhomogeneous underwater channel using various orders of QAM and PSK based OFDM techniques, have been reported in open literature. However, their bit error rate performances still need to be improved. Coding, when combined with OFDM, helps to detect and correct errors without having the overhead of too many retransmissions, as the bandwidth is a scarce resource in undersea scenario. The technique of interleaving, which is frequently employed in digital communication and storage systems to enhance the performance of the coding schemes, can be used to improve the error rate performance of the coded OFDM. The error rate performances of interleaved convolutional and BCH coded OFDMs for undersea acoustic links for binary phase shift keying and its differential variant have been studied in this paper. It is found that at high SNR, the process of interleaving and coding offers significant improvement in the error rate performance. It is also worth mentioning the fact that interleaving improves the performance of both convolutional and BCH coded OFDM systems.
