摘要

从增加信道容量的角度出发，研究了在复杂信号干扰条件下，将基于Tone Reservation (TR)的PAPR降噪算法与ofdm信号中减少频带干扰的方法联合应用的问题。与TR算法与降低频带干扰方法不一致的应用相比，将TR算法与保留音放置在频带干扰频率处的联合应用可以增加信道容量。与不加TR的ofdm信号相比，保留音排列密集的峰值平均功率比(PAPR)降低了。

Joint Minimization of Band Interference Influence and PAPR Value Reduction to Increase OFDM-System Capacity

The problem for joint application of PAPR reduction algorithm using Tone Reservation (TR) with methods to reduce band interference in OFDM-signals from the view point of increasing channel capacity in complex signal interference condition is considered. Joint application of TR algorithm with reserved tones placed at band interference frequencies is shown to increase channel capacity compared with inconsistent application of TR algorithm and methods to reduce band interference. Peak-to-Average Power Ratio (PAPR) reduction with reserved tones arranged densely compared with OFDM-signals without TR application is provided.
