B样条曲线曲面的生成与显示，用matlab实现(B-spline curve and surface generation and display, using matlab implementation)

1）了解小波分解与小波包分解概念区别与联系； 2）了解小波包的分解和重构算法积； 3）用matlab编程对信号进行小波包分解及小波能量图的绘制。 (1) to understand the wavelet decomposition and wavelet packet decomposition of differences and relations between concepts 2) to understand the wavelet packet decomposition and reconstruction algorithms of product 3) the signal using matlab programming wavelet packet decomposition and wavelet energy mapping.)

跑检距时距曲线，时距曲线，跑检距，平局速度的时距曲线与均方根速度的时距曲线比较(Run inspection from the time-distance curve, time-distance curve, running offsets, draw speed when away from the curve and the rms velocity-distance curve)

It calculates the Power Delay Profile of a multipath environment. A detailed procedure is given

高频地波雷达仿真的MATLAB程序，给出了图形界面(HF ground wave radar simulation MATLAB program gives the graphical interface)

波束形成就是从传感器阵列重构源信号。（1）、通过增加期望信源的贡献来实现；（2）、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复(From sensor array beamforming is reconstructing source signal.(1), by increasing the expected source contribution to achieve (2), by suppressing interference sources.Classic beamforming need observation direction (expected source direction).Blind beamforming is trying to not expect source direction information of source of recovery)

These are the code for energy detection.these code also describe about threshold,probability of detection,probability of false alarm,etc...

对语音信号进行分析时需要先进行预加重处理，起到提升高频的作用。(The speech signal analysis needs to first conduct a pre-emphasis process, to enhance the role of high frequency. )
