系统传输函数 用于系统传输简单模拟 了解传输过程(transfer in matlab)

用于对扩频滑动相关器信道检测的仿真，对127位的PN序列进行了仿真，载波频率2.4GHz( Spread Spectrum Sliding Correlator Channel Sounding )

High Accuracy Time Delay Measurements

采用Newmarke线性加速度法由加速度时程求位移、速度、加速度的反应谱及动力放大系数(β)谱(The response spectrum and dynamic magnification factor (beta) spectrum of displacement, velocity, acceleration are obtained by using newmarke linear acceleration method)

This source code is about how to encode and decode a picture using JPEG algriothm

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)
