Wireless communication system is rapidly enhancing by various techniques by many researcher, to meet the requirement of accurate and fast data communication in fading environment. The MIMO (Multiple Input Multiple Output) technique plays an important role in this direction. The use of MIMO technique will allow them to use higher order modulation for maintaining the errors in limits. This paper described one of the MIMO techniques orthogonal space time block code for improving the BER of the QAM modulation based communication in Nakagami fading environment. The results show a drastic improvement in the BER.
