MIMO-OFDM (Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing) system has been recognized as one of the most popular and competitive technique in a wireless environment now-a-days. The performance is calculated in terms of Bit Error Rate (BER) versus the Signal to Noise Ratio (SNR). In this paper, the authors discuss various algorithm to reduce ISI. They discuss the BER performance of the MIMO-OFDM system with four different equalizers (ZF, LMS, RLS and MMSE). The multicarrier modulation is used, which have advantages like Inter Symbol Interference (ISI) reduction, high data rate, greater reliability and good performance in multipath fading.
