watermark based on DCT

基于混合高斯模型的matlab代码，用于求概率问题，可行，已经运行过了(Based on Gaussian mixture model matlab code for the required probability problems, feasible and has been running over)

协作中继系统链路级仿真，里面对信噪比，误码率，BER性能仿真实现(Link Simulation cooperative relay system, which on the signal to noise ratio, bit error rate, BER Performance Simulation)

线性调频信号产生 带宽为240MHz 脉冲宽度为5us(Chirp signal bandwidth of 240MHz generate a pulse width of 5us)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

一种噪声辅助数据分析方法,包括随机梯度算法，相对梯度算法，模拟数据分析处理的过程，实现串口的数据采集，通过matlab代码，有详细的注释。

本设计研究了纠错码及循环冗余校验码的原理，以及利用MATLAB对其进行了编程和编译仿真，实现了CRC循环冗余校验码的编码及校验，在接收端收到通过校验的码.(This design research the error correcting code and cyclic redundancy check code principle, and the use of the MATLAB programming and compile the simulation, realized the CRC cyclic redundancy check code coding and check, at the receiving end received through the check code.)
