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.
