Multiple-Input Multiple-Output (MIMO) systems offer considerable increase in data throughput and link range without additional bandwidth or transmit power by using several antennas at transmitter and receiver to improve wireless communication system performance. At the same time, Orthogonal Frequency Division Multiplexing (OFDM) has becoming a very popular multi-carrier modulation technique for transmission of signals over wireless channels. OFDM eliminate Inter-Symbol-Interference (ISI) and allows the bandwidth of subcarriers to overlap without Inter Carrier Interference (ICI). A MIMO-OFDM modulation technique can achieve reliable high data rate transmission over broadband wireless channels. This paper deals with the analysis of a MIMO-OFDM system by using a MATLAB program. The performance of the system is evaluated on the basis of Bit Error Rate (BER) and Minimum Mean Square Error (MMSE) level.

In today's world, high speed is an important factor to be considered in wireless communication systems. This is because high speed is required for access of video, images, and many others multimedia application. One way to achieve high data rate is OFDM. Orthogonal Frequency Division Multiplexing (OFDM) is a technique which transmitted data parallel and this data are orthogonal to each other, hence result high data rate in wireless transmission as large no. of data is transmitted at same time. Another way is MIMO system. To increase the diversity gain or to enhance the system capacity on time-variant and frequency-selective channels, OFDM may be combining with multiple transmitter antenna and receiver antenna, this resulting MIMO OFDM system. MIMO-OFDM, a new wireless 4G technologies, has capability of enhance data rate transmission and robustness against multi-path fading. In this paper, two techniques Least Square (LS) and Minimum Mean Square Error (MMSE) are used to analysis the performance of MIMO OFDM System also used to reduce BER.
