【摘要】：針對(duì)傳統(tǒng)正交頻分復(fù)用降低峰均功率比算法計(jì)算復(fù)雜度較高,失真比較嚴(yán)重的問題,提出了一種改進(jìn)的限幅濾波算法,該算法將正交頻分復(fù)用信號(hào)劃分為奇信號(hào)與偶信號(hào)來(lái)分別進(jìn)行限幅濾波操作.仿真結(jié)果表明,與傳統(tǒng)的限幅濾波算法相比,該算法在降低峰均功率比(PAPR)的同時(shí),具有較低的計(jì)算復(fù)雜度,同時(shí)能較好地濾除帶外干擾,顯著提高系統(tǒng)的誤碼率的性能.
[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).
