Abstract:
1. A method of performing network coding in a network including K transmit-and-receive pairs and a relay including M antennas, each terminal included in the K transmit-and-receive pairs including N antennas, the method comprising: determining transmission beamforming vectors for the terminals included in the K transmit-and-receive pairs so that effective channels from the K transmit-and-receive pairs to the relay are aligned in independent dimensions, in response to the K transmit-and-receive pairs simultaneously transmitting signals; detecting the signals transmitted from the K transmit-and-receive pairs using the effective channels aligned in the independent dimensions; determining reception beamforming vectors for the terminals included in the K transmit-and-receive pairs so that the effective channels of the terminals included in the K transmit-and-receive pairs are aligned in the same dimension; and simultaneously transmitting network-coded signals for the K transmit-and-receive pairs, the network-coded signals being generated based on the detected signals.
