摘要:

Relay is a promising technology in wireless communications. There are several relaying modes for different channel conditions. In this paper, an adaptive relaying mode selection scheme jointly by destination and relay is proposed. The proposed scheme alters the signal forwarding mode at the relay station. It adaptively chooses among Amplify-and-Forward, Decode-and-Forward and direct mode according to Cyclic Redundancy Check (CRC) detection at relay and destination. Moreover, Block Error Rate (BLER) and throughput are adopted to evaluate system performance. The simulation results demonstrate that the proposed scheme significantly outperforms other existing relaying mode selection schemes.
