Wireless communication system is rapidly enhancing using various techniques by many researcher & to meet the requirement of accurate and fast data communication in fading environment. The MIMO technique plays an important role in this direction. It allows upto provide higher order modulation for maintaining the errors in limits. This paper describes one of the MIMO techniques namely orthogonal space time block code. This technique improves the BER of the QAM-16,QAM-32 and QAM-64 based communication in Rayleigh fading environment. The result shows an improvement in the BER.
