基于蚁群算法的图像边缘检测 MATLAB源程序

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)

用贝塞尔画曲线的demo，能够控制参数，调节曲线的形式(a demo using bezier)

该程序是信号的多普勒现象，通过设置不同的参数，可得到不同的现象，具有一定的参考价值。(that the procedure was the Doppler signal, by setting different parameters, will be different, has some reference value.)

根据输入的概率进行香农编码，然后输出必要的参数和编码的结果。其中有嵌套程序。(Probability under the Importation of Shannon coding, and then output the necessary parameters and the coding results. Which have nested procedures.)

the fast autocorelation function matlab code, used for basicallly pitch extraction and thus is extremely useful
