RayleighNoise_UniformNoise

：以系统仿真软件MATLAB中的Sin-mlink软件包为工具，完成了通信系统中超外差接收机的动态仿真，并得到了完整的 仿真结果，总结出了利用Sitmdink进行动态仿真的基本方法和步骤。(: A system simulation software in the MATLAB software package for the Sin-mlink tools, completed a communication system in the dynamic simulation superheterodyne receiver, and a complete simulation results, summed up the use of dynamic simulation Sitmdink basic methods and steps.)

文件包括1.维基百科中dirichlet distribution的资料2.产生服从dirichlet distribution分布的随机数的matlab程序。(This file consists of two documents.The first one is the content of dirichlet distribution wikipedia and the second one is a matlab procedure which can be used to generate a random number distributed to dirichlet distribution.)

采用Landweber方法进行反卷积，迭代次数需要自己设定(deconvolution with Landweber)

16psk通信系统的信噪比与误码率计算并绘图(16psk communication system signal to noise ratio and bit error rate calculation and mapping)

本人长期从事matlab中simulink在无线通信上的仿真（通信抗干扰国家重点实验室），此Turbo迭代译码程序是我见过的最经典的链路，过程非常的清晰，尤其迭代译码部分巧妙的利用降速率用最简单的结构实现了复杂的迭代过程，值得同行学习，必有极大收获！(err)

对图像进行JPEG压缩编码和解码，用matlab实现(JPEG compression of image encoding and decoding, using matlab implementation)

说明：  计算标记后物体的转角，条件：标记点大小能够区分。(To calculate the rotated angle of a marked object)

matlab中文帮助文档，独立于matlab软件运行(Chinese matlab help document, independent of the software to run matlab)

余弦变换压缩，用于图像压缩，压缩比高，且压缩后图像质量仍然很好。适用于灰度图象。(Cosine Transform compression for image compression, compression ratio, and compressed image quality is still good. Apply to the gray-scale image.)
