基于率匹配Turbo码的协作通信验证系统

摘要

A cooperative communication verification system with rate-compatible punctured Turbo codes is designed with C8051F120 and CC1101 in order to improve the transmission reliability of the short-range wireless communication system. In the system, the control node sends the control frame, and then the network synchronization is achieved. Coded cooperation scheme based on rate-compatible punctured Turbo codes is used at the source node and the relay node, coding gain and diversity gain are obtained simultaneously at the destination node using iterative decoding. Test results in the real environment show that, compared with point-to-point communication, the coded cooperative communication based on rate-compatible punctured Turbo codes can reduce the packet error rate significantly thus to improve the reliability of communication system.%为提高短距离无线通信系统的可靠性,基于单片机C8051F120和射频芯片CC1101设计了采用率匹配Turbo码的协作通信验证系统.在该系统中,控制节点通过发送控制帧,实现系统中所有节点的同步.源节点和中继节点采用基于率匹配Turbo码的编码协作方案,目的节点通过迭代译码,同时获得了编码增益与分集增益.实际环境中的测试结果表明,与点对点传输相比,基于率匹配Turbo码的协作通信传输方案能显著降低误包率,提高通信系统的可靠性.
