【摘要】：针对传统正交频分复用降低峰均功率比算法计算复杂度较高,失真比较严重的问题,提出了一种改进的限幅滤波算法,该算法将正交频分复用信号划分为奇信号与偶信号来分别进行限幅滤波操作.仿真结果表明,与传统的限幅滤波算法相比,该算法在降低峰均功率比(PAPR)的同时,具有较低的计算复杂度,同时能较好地滤除带外干扰,显著提高系统的误码率的性能.
[Abstract]:Aiming at the problem of high computational complexity and serious distortion of traditional orthogonal frequency division multiplexing (OFDM) algorithm to reduce PAPR, an improved amplitude limiting filtering algorithm is proposed. The orthogonal frequency division multiplexing (OFDM) signal is divided into odd signal and even signal. The simulation results show that compared with the traditional amplitude limiting filtering algorithm, the proposed algorithm has lower computational complexity while reducing the peak-to-average power ratio (PAPR), at the same time, it can filter out the out-of-band interference and significantly improve the performance of the system's bit error rate (BER).
