数学建模的算法大全，基于matlab，能让你使用起来，查询起来应用自如(Daquan mathematical modeling algorithm based on Matlab, allows you to use, query up the application with ease)

Program to encode in JPEG algorithm. Note, this doesnot output JPEG file. but a matlab demonstration of the process how jpeg is created.

说明：  短波信道watterson模型的建模仿真，已经编译通过。(The simulation of Watterson model of HF channel has been compiled.)

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)
