摘要

正交频复用(OFDM)的主要缺点之一是其峰均功率比(PAPR)。本文研究了在OFDM系统中进一步降低PAPR的分组编码削幅滤波方法。分析了该方法的误码率性能。仿真结果表明，与分组编码相比，分组编码的幅度裁剪和滤波方法提高了PAPR和BER性能。

A block coded amplitude clipping and filtering for peak-to-average power ratio in orthogonal frequency division multiplexing system

One of the major setbacks of orthogonal frequency multiplexing (OFDM) is its peak-to-average power ratio (PAPR). In this paper, an investigation of block coded amplitude clipping and filtering method to reduce further the PAPR in OFDM system is presented. The BER performance of this method is also analyzed. It is shown through simulation that the block coded amplitude clipping and filtering method improves the PAPR and BER performance as compared to a block coding technique.
