چکیده انگلیسی
Multi-hop transmission through wireless relays provides coverage extension and throughput enhancement. However, it may cause waste of bandwidth to meet half-duplex requirement of the relay. Motivated by this problem, we propose an efficient relaying scheme, referred to as partial relaying with layered encoding. In the proposed scheme, only partial information is transmitted via a relay, and a layered encoding is employed for the link between the source and relay for reliable delivery of the partial information. Simulation results confirm that the proposed scheme outperforms the conventional decode-and-forward relaying scheme, in terms of both the spectral efficiency and bit error rate.
