Description: echniques for multi-user detection in OFDM / MC-CDMA can be classified as linear or non-linear techniques. A number of these techniques have evolved from previous research for CDMA–based systems. The overlaying of OFDM with CDMA permits grouping of the received signals based on received power, and this fact is exploited by the techniques discussed below. This project is going to focus on some of the more recent advances in some of the non-linear multi-user detection (MUD) techniques. A brief summary of the various techniques are given below. (Maximum Likelihood detection is not discussed here because of the computation complexity involved.)-echniques for multi-user detection in OFDM/MC-CDMA can be classified as linear or non-linear techniques.

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.

Description: This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station,
with a constant speed such that the Maximum Doppler frequency is 5 Hz. The element spacings at the base station and mobile are one lambda and 0.5 lambda, respectively. The maximum angle spread at the base station is 4 degrees, whereas isotropic scattering is assumed around the mobile. The length of the simulated MIMO channel is 5 seconds, and any two adjacent samples are spaced by 0.01 seconds. For ensemble averaging, 90 realizations of the MIMO channel are generated.-This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station, with a constant speed such that the Maximum Doppler frequency is 5 Hz.
