说明：  简单实现基于加权分数傅里叶变换的混合载波系统(Simple Implementation of Hybrid Carrier System Based on Weighted Fractional Fourier Transform)

区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier transform to estimate the class LPF signal. It has higher learning value)

该程序实现水声信道的模拟方法及性能分析，提出了一种信的水声信道模型(The program implements underwater acoustic channel simulation methods and performance analysis, presents a letter of underwater acoustic channel model)

16位CRC校验原理与算法分析，很详尽，学习CRC16的重要资料。(16-bit CRC checksum algorithm theory and analysis, very detailed and important information to learn CRC16.)

横重要的leach 协议哦对你有很大的帮助 (Oh cross important leach agreement)

两种非参数估计方法 核估计 局部线性估计(kernel smoothing local constant regression )

说明：  实时声音采集，双通道采集声音信号，并且进行降噪处理和FFT变换(Real time sound acquisition)

说明：  温度报警系统程序，已经调试成功的，没有问题。(emperature alarm system program, has been successfully debugged, no problem.)
