This paper presents OFDM wireless communication system by using different equalization schemes. Performance and complexity are compared between pre-equalization, post-equalization and combined pre- with post- equalization (PPE) schemes. For combining technique, the received symbols are separated to pre- and post- symbols sequence by using the decision constellation splitter (DCS) algorithm. The result has shown performance in term of bit error rate (BER). In practice, channel estimation is not perfect so we also include the impact of imperfect channel estimation on BER performance in this paper.
