channel decoding in matlab

利用MATLAB编程，生成图像，随机生成一系列“囧”字(Using MATLAB to generate an image, a randomly generated series of " embarrassing" word)

CODE FOR COLOR IMAGE COMPRESSION USING QUANTIZATION ALORITHM. VECTOR QUANTIZATION.

AITKEN S INTERPOLATION Aitken s procedure yields systematically and successively better interpolation polynomials corresponding to successively higher order truncation of Newton s divided difference formula. Given a set of x and corresponding f(x), estimate f1(x1) f1= aitkenInterp(x,f,x1) f = corresponding function of x f1= corresponding function of x1

根据输入的相应数据，绘制数据的自功率谱幅值曲线图(According to the corresponding input data, drawing data from the power spectrum amplitude curve)

说明：  MATLAB编写的仿真小程序,关于STEP CONCROL的,仿真出CONTROL执行后的图形(MATLAB simulation prepared by the small program on STEP CONCROL. Simulation out CONTROL implementation of the graphics)

对一个一定范围内的数据进行分析,并画出直方图,程序很简单,书写不太规范,敬请谅解.(Painting histogram)

基于人工神经网络的常用数字信号调制，采用波束成形技术的BER计算，采用偏最小二乘法，相控阵天线的方向图（切比雪夫加权），使用matlab实现智能预测控制算法，本科毕设要求参见标准测试模型。( The commonly used digital signal modulation based on artificial neural network, By applying the beam forming technology of BER Partial least squares method, Phased array antenna pattern (Chebyshev weights), Use matlab intelligent predictive control algorithm, Undergraduate complete set requirements refer to the standard test models.)

利用FFT快速计算，线性排列阵子方向图。( This function computes and returns the gain radiation pattern for a linear array It uses the FFT to computes the pattern *INPUTS********** Nr ==> number of elements dolr ==> element spacing (d) in lambda units divided by lambda theta0 = steering angle in degrees winid ==> use winid negative for no window, winid positive to enter your window of size(Nr) win is input window, NOTE that win must be an Nr X 1 row vector nbits ==> number of bits used in the pahse shifters negative nbits mean no quantization is used *OUTPUTS****************** theta ==> real-space angle patternr ==> array radiation pattern in dBs patterng ==> array directive gain pattern in dBs ***************************************** )

说明：  仿真实现了十三位巴克码进行脉内调相。很好的程序，亲自优化过。(Thirteen Barker codes are simulated for intra-pulse phase modulation. Good procedures, personally optimized.)
