在无线数字通信中,信道衰落和多径传播效应引起的码间干扰,严重影响了通信的有效性和可靠性。单载波频域均衡(SC-FDE)是近几年发展较快的能够有效对抗多径效应的方法。文章基于MATLAB的仿真工具设计了一套实现单载波频域均衡技术的传输方案。与多载波传输系统—正交频分复用(OFDM)相比,该技术方案能够克服其所存在的不足,而且具有更好的误码性能和均衡效果。
In wireless digital communications, intersymbol interference caused by channel fading and multipath propagation has seriously affected the effectiveness and reliability of communications. Single-carrier frequency-domain equalization (SC-FDE) is a method that has been rapidly developed in recent years to effectively combat multipath effects. The article based on MATLAB simulation tool designed a set of single-carrier frequency domain equalization technology to achieve the transmission scheme. Compared with multi-carrier transmission system - Orthogonal Frequency Division Multiplexing (OFDM), the technical solution can overcome the existing shortcomings, and has better error performance and equalization effect.
