摘要
本文针对CMMB信号峰均值功率比很高的问题,研究了重复削波滤波算法在CMMB系统中的应用。仿真表明,这种算法可以有效地降低信号的峰均值功率比,同时还可以使系统性能获得一个增益。
In this paper,we have studied the method of repeated clipping and filtering to solve the problem of the high Peak-to-Average Power Ratio（PAPR） fo the CMMB signal.The simulation shows that this method can reduce the PAPR of the signal effectively,while the system can obtain a performance gain.
