In order to reduce thecalculation load introduced by optimum PTS method, m-sequence offinding the optimum side information can be utilized, which will notbring very heavy burden to the OFDM system since the cal- culationcomplexity is determined mainly by the number of IDFT at the cost ofPAR distribution performance of OFDM system.展开更多

The couple ratio, the self-ring effect, the Multiple-Access Interference (MAI), and the channel noises are the main factors degrading the system performance. We develop a systematic method that employs the smallest p multiplication method to analyze the optimization of the ring network. The results show that choosing an optimal couple ratio and power control will enhance the system performance dramatically. In addition, the “self-ring” interference and MAI can be suppressed by power control to some extent.展开更多
