Description: This script runs a simulation loop for either a linear or a DFE equalizer. It
uses the RLS algorithm to initially set the weights, then uses LMS thereafter to minimize execution time. It plots the equalized signal spectrum, then generates and plots BER results over a range of Eb/No values. It also fits a curve to the simulated BER points, and plots the burst error performance of the linear and DFE equalizers. The adaptive equalizer objects automatically retain their state between invocations of their \"equalize\" method.

Description: 信道均衡技术是移动通信中抗衰落的三大技术之一。均衡是用来解决由于信道的非线性和时变性引起的码间干扰的有效技术。如何有效解决码间干扰问题，具有重要的理论意义。 本文在介绍自适应均衡技术的基本原理和均衡研究现状的基础上，阐述了目前几种典型的自适应均衡算法及其它们存在的一些问题。文章在传统自适应算法的基础上，提出了两种改进算法：基于RLS的自适应MIMO-DFE算法和基于分数间隔的改进CMA+SDD算法。计算机仿真结果表明，两种算法的收敛速度快，稳态误差小，均衡效果与传统算法相比都取得了明显提高。-Channel equalization in mobile communications technology is the anti-fading of the three technologies. Balance is used to solve due to channel non-linear and time-varying inter-symbol interference caused by effective techniques. How to effectively solve the inter-symbol interference problem, has important theoretical significance. This paper introduces the basic principle of adaptive equalization and balanced study of the status quo, based on the current set of several typical adaptive equalization algorithm and some of the problems of their existence. Article in the traditional adaptive algorithm based on the proposed two improved algorithms: RLS-based adaptive MIMO-DFE algorithms and interval-based scores improved CMA+ SDD algorithm. Computer simulation results show that the two kinds of convergence of the algorithm fast, steady-state error is small, compared to equilibrium results with the traditional algorithms have achieved significantly improved.
