通信基本仿真3,适合初学者学习的代码,包括了调制,分析等等:使用IIR filter的经典模拟滤波器（巴特沃斯Butterworth,切比雪夫Chebyshev）,Bartlett周期图谱，加窗Bartlett周期图谱，基带波形仿真，IIR的贝塞尔滤波器Bessel Filter，二进制对称信道Binary Symmetric Channel仿真，比特序列，Remez滤波，BPSK复合基带信号仿真，载波生成器，椭圆滤波器Elliptical Filter，FFT,FSK调制及解调，高斯噪声Gaussian仿真，直方图，理想AM，线性PLL，BP混淆器，理想MPSK，正交振幅调变（QAM，Quadrature Amplitude Modulation），正交相移键控(QPSK)，Rayleigh Noise瑞利噪声，Yule-Walker Psd功率谱密度函数。(matlab simulte)

HHT变换的核心是EMD,在此项过程中通过EMD的编程和HHT的编程来实现了希尔伯特黄变换,可以看出处理此方法用来处理非线(The core of HHT transform is that EMD, realizes Hilbert Huang transform through EMD programming and HHT programming in this process. It can be seen that this method is used to deal with non-linear.)

次程序用来仿真线性调频脉冲下的一维距离像，可以对比压缩前后的目标回波信号(Second program is used to simulate the next chirp like a one-dimensional distance, you can compare before and after the target echo signal compression)

本程序的性能已经达到较高水平，用于特征降维，特征融合，相关分析等,对于初学者具有参考意义。( The performance of the program has reached a high level, For feature reduction, feature fusion, correlation analysis, For beginners with a reference value.)
