MIMO (Multiple Input Multiple Output) that use multiple antennas in transmitter and receiver is considered to be powerful technology in future wireless communication system. The major problem facing in this multipath propagation is the interference between symbols transmitted through adjacent channels. i. e. Inter Symbol Interference. This could be avoided if we use OFDMA (Orthogonal Frequency Division Multiple Access) technology. Thus MIMO combined with OFDM has got prior importance in future wireless communication system. The major properties of MIMO system involve Spatial Diversity and Spatial Multiplexing. In former case same copies of data is being transmitted in the MIMO channels while in latter case different user’s data is being transmitted in the MIMO channels. In this paper, a MIMO-OFDMA system with both the advantages of Spatial Diversity and Spatial Multiplexing is suggested.
