A Novel Channel Estimation and Equalization Technique for Two-Way MIMO Relay Communication System

In recent years the MIMO relay systems are more attracted. The MIMO relay system can maximize the mutual information between the source and destination. For all MIMO relay system the individual channel state information to be estimated. This paper introduce a technique for the efficient channel estimation. Superimposed training and pilot sequences estimate the channel and the equalizers are introduce to reduce the errors. The optimal power allocation is obtained by minimizing the MSE.
