A New Approach for High Data Rate Relay Transmission Using Multiple Antennas

Herein, we present a novel approach for high data rate transmission in a wireless network. The system includes a source, a destination and multiple relays. All nodes are equipped with multiple antennas. A half-duplex transmission protocol and a decode-forward transmission mode are deployed in the system. Our approach splits the data at the source into multiple independent data streams, and sends them to the destination via some selected relays at the same time. The relays are selected using an opportunistic approach based on spatially decomposing the channels and accessing the best modes. Simulation results show the benefits of our technique, particularly with correlated channels.
