| 摘 要： | 基于对称信道给出了解码中继方式下等功率分配协作通信系统的系统平均中断概率的精确表达式. 在衡量系统中断概率时，考虑了源到目的节点链路，指出考虑这一链路增益所获得的性能增益. 分析结果表明，最优功率分配系数受系统总可用功率和网络结构大小的影响.

| Abstract: | An analytical expression of the average outage probability on symmetric cooperative wireless networks is derived with consideration of the link gain between the source and the destination.Compared with schemes with no link gain,the study shows that it will improve the outage performance.Moreover,the power allocation problem is analyzed that the power is distributed equally between relays.It shows us that the optimal power allocation ratio is subjected to the total power in networks and to the networks size. |
