matlab滤波器,里面有三个方法滤波，用来滤波音频文件的(matlab filter, there are three ways to filter, for filtering the audio file)

model non linear of 10 bit Pipelined ADC

file is usefl for classification

多址接入协议仿真——都可以运行仿真出图！(Multiple access protocol simulation)

用于计算谱相关函数的频域平滑算法，可改参数，改输入信号类型(calculate spectral correlation function by using frequency smoothing Algorithm, you can change the parameters, and the type of input signal )

本程序利用K-wave实现了用一维线性阵列探测器采集到的光声信号数据完成2维光声图像重建。(This program implements the use of K-wave one-dimensional linear array detector photoacoustic signals collected data to complete two-dimensional photoacoustic image reconstruction.)

说明：  矩阵LU分解，非常方便的分解程序，简练而有效，希望大家下载(LU，derection，matlab NEWMark)

主要关于美国成功学专家成功学的经验介绍，让人摆脱困境，迎接新的人生！(Main expert on the U.S. success successful learning experiences, people bail out, meet new life!)

有关阵列天线的matlab仿真， 1、给出阵元的个数，阵元的间隔以及波长 2、计算方向图并绘制不同的方向图，有规律的排列 3、计算出主瓣宽度，3dB带宽，主瓣与第一旁瓣的幅度比（以dB作单位）(Array antenna matlab simulation, 1, to the number troupe, interval, and the wavelength of the array element 2, calculate the pattern and draw a different pattern, a regular arrangement of 3, calculate the width of the main lobe, 3-dB bandwidth of the main lobe and the first side lobe amplitude ratio (in dB as a unit))
