在本文中，我们提出了一种混合解码放大转发增量协作分集协议，使用基于信噪比的中继选择。在该协议中，当目的节点接收到源节点的信号失败时，选择一个采用混合解码-放大-转发技术的中继节点对信号进行解码。我们推导出中断概率和平均信道容量的近似闭式表达式。蒙特卡洛仿真验证了理论结果，并与直接传输协议和传统的增量中继协议的性能进行了比较。
In this paper, we propose a hybrid decode-amplify-forward incremental cooperative diversity protocol using SNR-based relay selection. In the proposed protocol, whenever destination unsuccessfully receives the source's signal, one of relays that exploit hybrid decode-amplify-forward technique is chosen to retransmit the signal. We derive approximate closed-form expressions of outage probability and average channel capacity. MonteCarlo simulations are presented to verify the theoretical results and compare the performance of the proposed protocol with the direct transmission protocol and conventional incremental relaying protocols.
