MATLAB 画的阵列信号方向图。 包括权都是1的方向图和用户修正方向图。(Array signal direction of MATLAB to draw figure. Including rights are fixed direction figure 1 in the direction of the figure and users.)

说明：  自己练习编写的波动方程，不知道行不行，求指正，求批评(wave equation)

说明：  基于MATLAB/GUI的M-QAM调制解调及误码率,本文件是在MATLAB2009a版本上设计的，低于此版本的有可能会出错。 此文件中“M_QAM.m”是主文件，其他均为调用文件,该程序实现了MQAM的调制解调功能，并画出了每一步的波形 (Based on MATLAB/GUI s M-QAM modulation and demodulation and bit error rate, this document is designed MATLAB2009a version, this version is lower than might be wrong. This file is in the " M_QAM.m" is the main document, others are calling the file, the program implements the MQAM modulation and demodulation functions, and draw the waveform of each step)

Inter-symbol interference if not taken care off may cause severe error at the receiver and the detection of signal becomes difficult. An adaptive equalizer employing Recursive Least Squares algorithm can be a good compensation for the ISI problem. In this paper performance of communication link in presence of Least Mean Square and Recursive Least Squares equalizer algorithm is analyzed. A Model of communication system having Quadrature amplitude modulation and Rician fading channel is implemented using MATLAB communication block set. Bit error rate and number of errors is evaluated for RLS and LMS equalizer algorithm, due to change in Signal to Noise Ratio (SNR) and fading component gain in Rician fading Channel.
