[matlabSingle_Carrier_FDMA(SC-FDMA)matlab

Description: Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA(主要用于下行),其最大的优势在于低峰值平均功率比(即PAPR)。本程序包括OFDMA,SC-FDE(单载波频域均衡)以及SC-FDMA程序,接收端采用经典的ZF和MMSE检测算法,程序短小精悍,相当经典,方便该领域的人学习与研究。-Single Carrier FDMA or SC-FDMA, also known as DFT-Spread-OFDM is the latest 3GPP LTE uplink transmission for a new program. Compared to OFDMA (mainly used for the downlink), the biggest advantage lies in its low peak-average power ratio (ie, PAPR). This procedure, including OFDMA, SC-FDE (single carrier frequency domain equalization), as well as SC-FDMA procedure, the receiving end the use of classical ZF and MMSE detection algorithm, procedures dapper, very classic, convenient in the field to learn and research.

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: Ajey, S., B. Srivalli, et al. (2010). On performance of MIMO-OFDM based LTE systems. Wireless Communication and Sensor Computing, 2010. ICWCSC 2010. International Conference on. 4G wireless systems predominately employ multiple input multiple output (MIMO) with an orthogonal frequency division multiplexing (OFDM) system. Like other 4G systems long term evolution (LTE) also employs MIMO-OFDM physical layer. MIMO helps in increasing the throughput whereas OFDM converts a frequency selective fading channel to multiple flat fading sub-channels facilitating easy equalization. It is proposed that LTE system should mandatorily support 2Ã — 2 MIMO setup. Our paper focuses on the performance of such a LTE system with two transmit antennas and two receive antennas in a frequency selective fading environment.
