carlight1中是一个用C编的程序，用于计算每条光线在测试屏上的坐标(carlight 1 is a C series of the program, each ray is used to calculate the coordinates on the screen in the test)

Short Term Energy is important for filtering a signal. With Short Term Energy, we can get voiced and unvoiced.

TRACKING RADARS PRESENTATION

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.

用于描述交通流的元胞模型，能很好的仿真模拟(Used to describe the traffic flow cell model can be a good simulation)

说明：  实现匹配滤波仿真的两个程序，每个程序生成四个图，可以通过比较验证信号的时延不影响匹配滤波的输出信噪比，及不同信号信噪比与信号波形无关，只与信号能量有关(Matched filter to achieve the two simulation procedures, each of the programs to generate the four plans, you can verify by comparing the signal delay does not affect the matched filter output signal to noise ratio, and different signal-noise ratio and signal wave has nothing to do only with the signal energy relevant)
