说明：  这个程序是描述了跳频系统在部分边带干扰下的BFSK系统的仿真，主要是误码率计算函数(This procedure is described in some side-band frequency-hopping system under the disturbance of the BFSK system simulation, bit error rate is mainly a function)

hdf5数据的读取等功能，现有hdf多为hdf4，hdf5有自身的读取和操作程序，如针对风云数据等(Read other functions hdf5 data, the existing hdf mostly hdf4, hdf5 have read and operate their own programs, such as data, for FY)

连接一起的下半部分是传统一次调频系数的仿真，参数如算例所示，上半部分是其改进一次调频系数后的仿真，最后由示波器观测波形的不同。(The lower half of the connection is the simulation of the traditional primary frequency modulation coefficient. The parameters are shown in the example. The first half is the simulation after the improvement of the primary frequency modulation coefficient, and finally the waveform is observed by the oscilloscope.)

这是一本非常好的书，对于学习matlab非常有用处，（用超星阅读器打开）(This is a very good book for learning matlab very useful, (with Chaoxing Reader to open))

Image Encryption based on the RGB PIXEL Transposition and Shuffling Abstract — Privacy is one of the key issues information Security addresses. Through encryption one can prevent a third party from understanding raw data during signal transmission. The encryption methods for enhancing the security of digital contents has gained high significance in the current era of breach of security and misuse of the confidential information intercepted and misused by the unauthorized parties. This paper sets out to contribute to the general body of knowledge in the area of cryptography application and by developing a cipher algorithm for image encryption of m*n size by shuffling the RGB pixel values. The algorithm ultimately makes it possible for encryption and decryption of the images based on the RGB pixel. The algorithm was implemented using MATLAB. Index Terms — Cryptography, Encryption, algorithm, cipher image
