amplitude modulation system using simulink matlab

sample program in feedback and control systems for electronics engineering students in malayan colleges laguna

今天上传《数学实验与Matlab》程序，希望对大家有用！(today uploaded "Matlab mathematical and experimental" procedures in the hope that it may be useful right! Thank you!)

一本matlab的英文自学书籍，分四个部分，详细介绍了matlab的使用方法及一些实例！(Matlab an English self-study books, is divided into four parts, described in detail the use of matlab and some examples!)

现代信号处理的书籍。信息类人员必读书籍。里面的许多信号处理模型可以用matlab实现仿真(Modern signal processing books. Information on categories of persons reading books. Many signal processing model which can be used for simulation matlab)

matlab数字信号处理实例；MATLAB下的数字信号处理实现示例(matlab digital signal processing examples MATLAB under the sample implementation of digital signal processing)

matlab 光线追迹，算法比较简单，可供初学者看看。(Matlab ray tracing, the algorithm is relatively simple, for beginners to see.)

四节点单元刚度矩阵，使用matlab编制，上传的是m文件。(QuadraticQuadElementStiffness，by matlab )

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.
