SUM RATE MAXIMIZATION:
TWO-WAY relay systems in wireless networks have received significant attention due to their high spectral efficiency.To enhance the data rate of non regenerative two-way relay systems, beam forming design schemes were studied based on the iterative method and channel parallelization. a new algorithm using the MSE duality is proposed that maximizes the sum rate for a non regenerative multiple-input multiple-output (MIMO) two-way relay system
Fig: Relay system
beam forming problem to maximize the sum rate is non-convex we present the per stream MSE duality for the MIMO two-way relay system and exploit the alternate algorithm using the MSE duality and convex optimization programming.The linear beam forming design was investigated to maximize
the sum rate of an MIMO two-way relay system. We derived the per stream MSE duality in the two-way relay system under cross power constraints. A novel iterative algorithm was developed using the per stream MSE duality and convex optimization programming to jointly optimize the linear transceivers.
In general, a half-duplex relay is preferable to full-duplex relay from an implementation aspect, but leads to a loss of spectral efficiency because the transmission and reception require orthogonal time resources. To overcome the loss of spectral efficiency, a two-way relay channel (TWRC), which completes an exchange of messages between two source nodes over two time phases,
