说明：  matlab中similink入门指南。希望能够大家有些帮助，尤其对于刚刚入门的朋友。(matlab in similink Getting Started Guide. Some hope to be able to help everyone, especially for entry-just friends.)

特征提取的几种算法程序，应该对图像处理有很大用处。不妨试试。(The algorithms for feature extraction procedure should be very useful for image processing. Worth a try.)

将一张图片嵌入到另一张图片中，并提取出来(LSB 算法)(Embed a picture into another picture, and extracted it (LSB algorithm))

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

采用离散余弦变换和霍夫曼编码，对图像进行压缩存储，并且完成解压缩(Discrete cosine transform and Huffman coding, the image compression and storage, and complete decompression)

选取CDMA通信系统中的接入信道部分进行仿真与分析。首先，通过学习相应的理论知识，熟悉接入信道实现的过程，对每一步的原理有了较深的理解，同时，也对MATALB软件进行熟悉和了解，对MATLAB软件中的SIMULINK部分及其内部的CDMA模块用法和参数设置进行熟悉，然后运用MATLAB软件对接入信道部分进行设计，并逐步地对各个模块进行分析、仿真与验证。目的是通过毕业设计工作熟悉现代无线通信系统的基本构成与基本工作原理(CDMA communication system to select the access channel simulation and analysis of parts. First of all, by learning the theory of knowledge, familiar with the access channel to achieve the process, with each step deeper understanding of the principle, at the same time, but also familiar with the software MATALB and understanding of the MATLAB software and its internal part of the SIMULINK use of the CDMA module and parameter settings are familiar with, and then use MATLAB software to access parts of the design of channel and step by step analysis of each module, simulation and verification. The purpose of design work through graduate familiar with the modern wireless communication systems constitute the basic and fundamental principle,)
