Performance Analysis of Different QAM Techniques Using Rician Fading Channel

Wireless communications is one of the most active areas of technology development of our time. This development is being driven primarily by the transformation of what has been largely a medium for supporting voice telephony into a medium for supporting other services, such as the transmission of video, images, text, and data. In this paper QAM modulation techniques used for calculation of SNR with MIMO system using fading channel. This work presents, a simulation toll MATLAB R2013a to study the performance analysis of Bit Error rate BER V S Signal to Noise ratio SNR .
