| 摘 要： | 针对协作通信网络中的信道时变特性，以系统错误概率为准则，设计了一种新的系统方案．根据编码函数，对不同信道上的发送信号选择具有最佳汉明距离的纠错码进行保护，使系统错误概率最小．在此基础上，采用时变功率分配算法对信源节点和中继节点的发送功率进行优化分配．理论分析及仿真结果表明，该方案可使帧错误性能改善07 dB．

| Abstract: | Considering the channel time variant property in cooperative communication networks,a new system scheme is designed based on the system error probability.According to the encoding function,the error correct code with optimal hamming distance is chose for different channel in order to minimize the system error probability.Furthermore,the time variant power allocation algorithm is used to allocate the transmit power between the source node and relay node.Analysis and simulate show that the proposed scheme can... |
