摘要

为了降低实现复杂度，提出了一种有效降低WiMAX系统峰均功率比(PAPR)的方法。首先对WiMAX系统进行过采样，然后进行归一化，最后对信号进行剪辑和滤波。本文讨论了在降低PAPR、带外辐射和误码率性能方面的改进。仿真结果表明，该方法可以有效地降低WiMAX系统的PAPR

An Efficient Peak-to-Average Power Ratio Reduction Algorithm for WiMAX System

In order to decrease implementation complexity, a method which can effectively reduce the peak-to-average power ratio (PAPR) of the WiMAX system is proposed. We firstly oversample the WiMAX system, then normalize, finally clip and filter the signals. Improvements on PAPR reduction, out-of-band radiation and bit error rate performances are discussed in this paper. Simulation results show that the proposed method can effectively reduce the PAPR of WiMAX system
