spread spectrum and despread

产生QPSK的简单程序，先产生0到3的随即数字，用这些数字产生相位，然后产生QPSK信号！(Get QPSK！)

自己编写的彩色图像分水岭分割代码，希望对大家有帮助。(I have written the code for color image watershed segmentation, we want to help.)

基于SVM的人脸检测。优化了部分代码。可以参考一下，各位亲们。(SVM-based face detection. Optimize the part of the code. Reference, you pro.)

基于状态空间模型的预测控制程序，参考了钱积新的《预测控制》(Predictive control program based on state space model, refer to the Qian Jixin’ s predictive control )

使用快速FFT求序列平均周期.输入时间序列，返回快速傅里叶变换FFT计算出的序列平均周期。求混沌序列最大Lyapunov指数时，要求序列平均周期。(Fast FFT request sequence the average cycle)
