| 摘 要： | 提出了一种基于系统总误码率的协同伙伴选择算法。当系统总发送功率一定时,通过系统误码率公式,采用带CRC校验的DF协同通信的协同增益,来降低系统总的误码率。仿真表明,此算法有效地降低了系统总误码率,并且系统SNR越大,协同通信对系统数据传输的帮助越明显。

| Abstract: | In this paper,a partner selection algorithm based on the total system error has been proposed.According to the system error rate formula,we can get the cooperative gain when total transmit power is fixed,and the system use a CRC checksum and DF cooperative communication,through this algorithm to reduce the system BER.The simulation shows that this algorithm can effectively reduce the total system bit error rate,and the greater the system SNR is,the more obvious help cooperative communication can give for da... |
