摘要：
Relay communication has been receiving considerable attention for its advantage of extension in communication coverage and enhancement of communication performance. In this Letter, the author studied the performance of dual-hop communication systems with a decode-and-forward protocol. The author first analyses the performance of dual-hop communication systems with various modulation schemes. Then, the author found the optimum energy allocation depending on the relay location for each modulation scheme. Finally, the performance of dual-hop communication systems with equal energy allocation and optimum energy allocation was compared.
