Efficient Partial Relaying Protocol for Wireless Multi-Hop Transmission

초록

We propose a multi-hop transmission protocol suitable for the reverse link of cellular systems. The proposed protocol, referred to as cooperative multiplexing with partial relaying (CM-PR), is based on relaying of partial information bits followed by cooperative multiplexing. The CM-PR protocol provides path loss reduction and spatial diversity gain without any loss in the spectral efficiency, in contrast to the conventional decode-and-forward protocol or its variants that cause bandwidth expansion to attain such benefits. Simulation results confirm that the CM-PR protocol significantly outperforms the direct transmission in terms of the bit error rate, especially when a relay is close to the source.
