摘要

正交时频空（Orthogonal Time Frequency Space，OTFS）调制因其在高移动性场景下的可靠传输能力，已成为6G无线通信系统的空口候选波形之一。但是，作为一种多载波调制技术，OTFS也面临着峰均功率比（Peak to Average Power Ratio，PAPR）过高的问题。迭代削峰滤波（Iterative Clipping and Filtering，ICF）峰均比抑制方法能够以较低的复杂度实现PAPR的有效抑制，但滤波操作在消除带外辐射的同时，会滤除削峰产生的高频分量，并对时域波形进行平滑重构，使得部分样点幅度重新超过削峰门限，从而产生峰值再生现象，限制PAPR抑制性能。针对该问题，本文提出了一种基于预编码的ICF峰均比抑制方法。该方法利用Zadoff-Chu（ZC）预编码改善信号幅度分布的统计特性，降低削峰噪声功率，进而抑制滤波导致的峰值再生，从而有效提升ICF的峰均比性能。仿真结果表明，在相同迭代次数下，提出的基于预编码的ICF方法可以有效提升PAPR抑制性能，同时在高动态场景下改善误码率（Bit Error Rate，BER）性能。

Abstract

Due to the reliability under high-mobility scenarios

Orthogonal Time Frequency Space (OTFS) has become one of the candidate waveforms for sixth-generation (6G) communication systems. However

as a multi-carrier modulation technology

OTFS faces the issue of high peak-to-average power ratio (PAPR). Iterative clipping and filtering (ICF) can effectively suppress PAPR with low complexities. However

the filtering operation induces peak regrowth. To improve the PAPR performance of ICF

this paper proposes a precoding-based ICF scheme aiming at suppressing peak regrowth. Building upon the use of ZC precoding to improve the amplitude distribution of OTFS signals

the scheme employs ICF to effectively suppress peak amplitudes. Simulation results demonstrate that

under the same number of iterations

the proposed precoding-based ICF method effectively improves PAPR suppression performance while improving bit error rate (BER) performance in high-mobility scenarios.
