摘要

由于卫星通信体制的约束，接收机信号处理在时域进行，致使传统信道均衡算法面临高维矩阵求逆困境。充分利用Toeplitz矩阵的特殊结构和连续干扰消除思想，提出了一种低复杂度单载波时域均衡算法，将高维信道均衡系统转换成多个低维信道均衡系统，依次对低维信道均衡系统进行均衡，从而避免对高维矩阵求逆操作。实验结果表明，与传统信道均衡算法相比，所提算法能以更低的计算复杂度实现更相近甚至更优的误码性能。

Abstract

Due to the constraints of the satellite communication systems

the receiver signal processing was carried out in the time domain

which made traditional channel equalization algorithms face the challenge of high-dimensional matrix inversion. Taking full advantage of the special structure of Toeplitz matrix and the idea of successive interference cancellation

a low-complexity single carrier time domain equalization algorithm was proposed to avoid high-dimensional matrix inversion

by converting the high-dimensional channel equalization system into multiple low-dimensional channel equalization systems and performing channel equalization successively. Simulation results show that compared with the traditional channel equalization algorithms

the proposed algorithm can achieve similar or better performance with lower complexity.
