Abstract

We propose multi-user cooperation schemes in which all cooperating users simultaneously forward their partners' signals that are successfully decoded to a multi-antenna destination to achieve high bandwidth efficiency. Various suitable signal processing and decoding techniques at the relay and at the destination are considered. Simulation results show that the proposed schemes significantly outperform direct transmission and reference schemes under the same transmit power and bandwidth efficiency.
