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: 多天线正交频分复用(MIMO-OFDM,Multiple-Input and Multiple-Output Orthogonal Frequency Division Multiplex)系统中,精确的符号定时同步可使接收端解调数据时消除载波频率偏移和符号间干扰。而由于MIMO空间信道复杂度较高,使得单天线OFDM系统的同步方法不能直接应用于MIMO-OFDM系统中。提出的两步同步方法首先利用时域导频作为第一步同步进行粗同步,然后利用循环交织前缀作为第二步同步对每一个MIMO-OFDM符号进行同步偏差调整。需要指出的是,两次同步过程均可以产生尖锐的相关峰,使得同步精度大为提高。-Accurate timing synchronization of symbol is important for MIMO-OFDM system,and it can eliminate the integral frequency shift of carrier and intersymbol interference.Two-step timing synchronization method is proposed in this thesis.First,the time-domain pilot is employed to obtain coarse timing synchronization,then the interleaved cyclic prefix and maximum likelihood estimation method are adopted to adjust the synchronization difference,through which the correlational characteristic of that window could be ...

Description: With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication, the role of MIMO detectors plays an important part to remove inter-symbol interference (ISI) caused by multipath fading channel. In this paper the BER performance of IEEE 802.11n for 3x2, 4x2 and 4x3 antennas are compared using MMSE and ZF detectors in Matlab Simulink. Platform: |
