摘要:Multiple-input¨Cmultiple-output (MIMO) technology is a recent breakthrough in wireless communications and has been shown to enhance channel capacity in single user systems.Multiple input multiple output (MIMO) orthogonalfrequency division multiplexing (OFDM) systems ease highdata rate communications. The use of multiple antennas at both the transmitter and receiver can considerably increase the channel capacity. These systems are called the multiple-input multiple-output (MIMO) systems. By using orthogonal frequency division multiplexing (OFDM) transmission techniques, the MIMO-OFDM system can achieve high spectral efficiency, throughput which makes it irresistible for high-data-rate wireless applications. In this paper we study the equalization problem for multiple-input multiple-output (MIMO) systems & by using numerical results simulated performance of the equalization techniques for MIMO systems is carried out & it is shown that BER(Bit Error Rate) decreases as number of receiving antenna increases.
