Frequency-conversion

线性调频信号的维格纳分布，伪WVD，平滑WVD比较，并且给出维格纳分布三维表示。方便学习LFM信号。(Linear frequency modulation signal of the wigner distribution, pseudo WVD, smooth WVD comparison, and give the wigner distribution 3 d said.Convenient learning LFM signal.)

GPS信号的产生程序，简单易懂，很快就可以掌握GPS信号格式及生成方法。(GPS signal generation process, simple and easy to understand, will soon be able to master GPS signal format and the generation method.)

数字通信中经常用到的几种调制方式仿真，包括ASK调制，OOK调制，FSK调制，BPSK调制等，将该代码理解透彻能够对数字系统中的调制解调方式有着更深入的认识，绝对的好东西，有时间会效代码中的各条语句添加上注释(Frequently used in digital communication several modulation simulation, including the ASK modulation, OOK modulation, FSK modulation, BPSK modulation, a thorough understanding of the code for digital modulation and demodulation system has a more in-depth understanding of the absolute good things, time will be valid code on each statement to add comment)

matlab实现16QAM调制解调的程序(matlab realize 16QAM modulation and demodulation procedures)

本程序实现两幅图象的渐变，利用的是图象多项式扭曲技术，里面已包含图片(the program changed two images using the polynomial distorted image technology, which includes Photo)

阵元数16下均匀圆阵的零限形成，先建立约束函数，再创建目标函数，计算零陷(Element number 16 under the Uniform Circular Array of zero-threshold shape, to create constraint function, and then create the objective function, calculated Null)
