摘要

正交时频空（orthogonal time frequency space，OTFS）技术是近年来出现的一种新型多载波调制技术。在 OTFS 技术中，数据信号在时延—多普勒域产生，经过逆偶有限傅里叶变换实现信号的时频二维扩展，以解决正交频分复用（orthogonal frequency division multiplexing，OFDM）技术在时频双选信道下干扰严重的问题。介绍了OTFS技术的基本原理，通过仿真验证其相比于OFDM技术的优势。对其研究现状进行分析总结，指出 OTFS 技术中的多址接入、信道估计和线性接收机等研究方向目前有待解决的问题。对 OTFS 技术在雷达—通信一体化系统中的应用前景进行分析和展望。

Abstract

Recently

a new multi-carrier modulation technique termed orthogonal time frequency space (OTFS) was proposed.In the OTFS modulation

the data symbols are modulated at the delay-Doppler plane and spread on all the time-frequency resource elements with the inverse symplectic finite Fourier transform.Compared with the conventional orthogonal frequency division multiplexing (OFDM) technique

the OTFS modulation performs better in the time-varying and frequency-selective channel.The state of art of OTFS was reviewed and summarized.Simulation results were presented to demonstrate the performance advantage of OTFS over the conventional OFDM.The remainder problems of multi-accessing

channel estimation and linear equalization in OTFS was given.The application of OTFS signal in joint Radar and communication system was also analyzed.
