Abstract :
A novel transmission scheme that mixes half-duplex decode-and-forward relay transmission (RT) with direct transmission (DT) is proposed for a MIMO relay channel. In this scheme, the source message is divided into two parts: one for DT and the other for RT. Preceding and decoding schemes are considered to convert the original relay channel into several parallel subchannels so that resource allocation can be easily performed for RT and DT. Simulation results show significant average capacity gain of the proposed scheme over pure DT scheme and pure RT scheme.
