关于MATLAB的仿真的一些资料，非常完整，很不错全面的(MATLAB simulation on some of the information, very complete, very good overall)

demodulate_sig 解调 generate_noise 叠加高斯噪声 insert_value 插值 modulate_to_high 调制到载波 pick_sig 采样 plot_2way 绘制正交信号图 plot_astrology 绘制星座图 plot_snr 绘制误码率曲线图 project 主函数 Qam_modulation QAM调制函数 rise_cos 升余弦滤波 stem_2way 绘制滤波后的信号图 (qam matlab simulation)

说明：  最小主瓣的Beamforming 利用的cvx优化(CVX optimization of beamforming utilization with minimum main lobe)

matlabde zbt price 函数类似与bootstrapping法求利率期限结构(zbt price bootstrapping)

The folder contains programs i have written for my project and in college..

功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)

计算目标和海洋回波的功率谱密度,该函数用来计算任意函数的一阶偏导数(数值方法),迭代自组织数据分析。( Calculating a target and ocean echo power spectral density, This function is used to calculate the arbitrary function of the first order partial derivative (numerical methods), Iterative self-organizing data analysis.)

遗传算法的实现，里面有详细代码的说明，关于选择交叉和变异(The implementation of genetic algorithm, there is a detailed code of instructions, about the selection of crossover and mutation)

matlab的一些接口程序！希望对学习matlab的同仁们有所帮助~(some matlab interface program! Want to learn matlab help colleagues ~)

this file give different codes of modulation
