Conference : ITC-CSCC 2011 
Abstract : We consider an amplify-and-forward (AF) halfduplex relaying system which consists of one source and destination pair with M antennas, and K relay nodes with a single antenna. To enhance the capacity of AF relaying system, we propose spatial multiplexing strategies selecting M relay nodes and transmitting M data streams. Two spatial multiplexing strategies are considered according to the knowledge of channel state information (CSI) at the source. Furthermore, to reduce the computational complexity of multiple relay selection efficiently, we propose a sub-optimal selection algorithm. Simulation results show that the proposed strategies achieve more capacity gain as the number of relay nodes increases. In addition, the suboptimal selection algorithm also achieves the multiplexing gain with a small loss compared to the exhaustive search algorithm.
