Abstract
The utilization of the combination of multiple antennas with the orthogonal frequency division multiple access technique called the MIMO-OFDM in wireless communication has improved the spectral efficiency and the coverage area. In wireless communication systems like MIMO-OFDM, the channel for the transmission of information could be varied quickly with time and may result in the loss of orthogonality of information signal causing ISI or overlapping of the signal bits. This would increase the bit error rate and the system performance degrades. In this paper we present performance comparison different equalizer techniques Zero Forcing Equalizer, minimum mean square error, maximum likelihood sequence estimation. The performance comparisons is shown in result section.
