主要是讲CIC补偿滤波的设计与理解，里面有数学推导和程序实例，希望对大家有用(cic compensation filter design)

说明：  A GUI matlab model for getting the ionex value

计算CDMA系统的误码率的最重要的函数，记得看哦，肯定有用(The most important function to calculate the error rate of the CDMA system, remember Kane, certainly useful)

经典的国外bitshop关于机器学习和模式识别教程，全是英文，内容详细(Classic foreign bitshop tutorial on machine learning and pattern recognition, all in English, detailed)

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)

一种简单的利用二阶信息来提高训练速度的快速传播算法，权值假设为独立的，下降过程可以对每个权值进行优化。(Use of a simple second-order information to improve the training speed of the fast-propagation algorithm, the right value is assumed to be independent, the process can decrease the value of each right to be optimized.)

对网格进行平滑，利用汉宁窗对海底地形进行平滑。直接输入函数即可。(Smoothing of the grid, the use of Hanning smoothing of the submarine topography. Can be directly input function.)

防积分饱和PID控制算法，MATLAB语言编写，仿真效果不错。(Anti-integral saturation PID control algorithm, MATLAB language, simulation results are good.)
