Implementation of Both Spatial Diversity and Spatial Multiplexing Technique in MIMO-OFDMA Communication System

Multiple Input Multiple Output (MIMO) that use multiple antennas in transmitter and receiver, 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 the users use Orthogonal Frequency Division Multiple Access (OFDMA) 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.
