	%X This paper deals with wireless relay communication
systems in which multiple sources transmit information to the
destination node by the help of multiple relays. We consider a
signal forwarding technique based on the minimum mean-square
error (MMSE) approach with multiple antennas for each relay. A
source-relay-destination joint design strategy is proposed with power
constraints at the destination and the source nodes. Simulation results
confirm that the proposed joint design method improves the average
MSE performance compared with that of conventional MMSE relaying
schemes.
