摘要 链路自适应算法利用统计的包错误率(PER)进行自适应的调整调制编码的方式,以使系统具有更高的吞吐量的同时,提高系统频谱的利用率,更好的满足未来宽带无线通信的传输要求。同时具有较小的时延抖动,适合TCP业务的传输。 In this paper, the link adaptation is based on the statistic variable PER to adaptively adjust the efficiency of coding and transmission, it can obtain the higher throughput and save the spectrum resource. Moreover, the technology is characteristic as small jitter , it can satisfy the demand of high data rate in future communication system.
