“…The goal of channel coding is to improve the bit error rate (BER) performance of power limited and/or band limited channels by adding redundancy to the transmitted data. The three channel coding schemes [13], that are modified to achieve objective of this work are described in the following section:…”

Modern OFDM systems provide effective spectral usage by allowing overlapping in the frequency domain. Moreover, it is highly resistant to multipath delay spread. The suppression of inter-symbol interference (ISI) is one of the top features of OFDM. It also facilitates mobile bandwidth allocation and may increase the capacity in terms of number of users. Even though the presence of OFDM's built in error preventing mechanism; error tends to occur that averts delivery of proper signal. In this work we evaluated and adapted ways of fine-tuning for different error correction methods so that they may bring positive impact on communication systems who are developing and using OFDM. Here the performance of different known error correcting techniques for OFDM systems have been analyzed after extending and puncturing feature is applied on them. Simulations are performed in well-known simulator MATLAB to evaluate the modified techniques for different channel conditions. As the advantage of OFDM based systems are mainly the robustness to channel impairments and narrow-band interference; thus added error reduction models will improve significant efficiency of systems based on OFDM.

“…The power of error correcting codes increases with the channel coding length constraint and approaching the Shannon limit with a large number of length constraints. But in return the complexity of the decoder also increases with length constraint [23]. For these reasons, it is desirable to construct long codes and minimize the complexity of the decoder.…”

In past decades, there has been a growing interest in the discussion and study of using underwater acoustic channel as the physical layer for communication systems, ranging from point-to-point communications to underwater multicarrier modulation networks. A series of review papers were already available to provide a history of the development of the field until the end of the last decade. In this paper, we attempt to provide an overview of the key developments, both theoretical and applied, in the particular topics regarding multicarrier communication for underwater acoustic communication such as the channel and Doppler shift estimation, video and image transmission throw multicarrier techniques, etc. This paper also includes acoustic propagation properties in seawater and underwater acoustic channel representation.

“…Binary phase shift keying (BPSK) technique has helped to achieve better BER performance. In [7], Haque et al studied the effect of various combined FEC codes on the performance of a wireless orthogonal frequency division multiplexing (OFDM) system. In this study, the authors used Reed-Solomon (RS) (255, 239, 8) encoder, Cyclic (15,11) encoder, Bose-Chaudhuri-Hocquenghem (BCH) (127, 64) encoder and ⅔ and ¾ encoders of convolutional coding for channel coding.…”
