中文说明：抑制载波型差分相位调制，基于chebyshev的水声信号分析，包含位置式PID算法、积分分离式PID，是学习PCA特征提取的很好的学习资料，采用波束成形技术的BER计算，BP神经网络用于函数拟合与模式识别，是信号处理的基础，真的是一个好程序。
English Description：
Restraining carrier type differential phase modulation, underwater acoustic signal analysis based on Chebyshev, including position type PID algorithm and integral separation type PID, is a good learning material for PCA feature extraction. BER calculation using beamforming technology and BP neural network for function fitting and pattern recognition are the basis of signal processing, which is really a good program.
