At the same time, the different degradation in the radio link, the partial transmit sequence under stochastic power control in Multi-user OFDM system is proposed. At last, the performance of the PAPR is analyzed。
但是多用户OFDM系统中由于使用的是多载波调制,系统中存在峰均比的问题,同时考虑到在传输过程中无线链路的衰落不同,本文提出了多用户OFDM系统中随机功率控制下的部分传输序列模型,并且对系统的PAPR性能进行了分析。
