这个压缩包括了通信系统的仿真建模原理，以及信道的模型，对初学者和有帮助！(This compression includes the principles of communication systems, simulation modeling, and channel models, for beginners and helpful!)

this is main program of tomography modelling

说明：  使用MATLAB完成的经典的BPNN算法，在神经网络的课程学习上有很好的帮助(Use MATLAB to complete the BPNN classical algorithms, neural networks in the courses have a good help)

New for AlGaAs/GaAs quantum well

说明：  the code is dealing with the detection of faces in an image. it is basically a face detection code

运用丹麦法对实验数据进行抗差估计，适用于含粗差的数据(Danish Act on the use of experimental data robust estimation for data with outliers)

说明：  局部放电小波去噪，采用db5小波进行5层分解，最后重构信号(Partial discharge wavelet denoising, db5 wavelet is used for 5-level decomposition, and finally the signal is reconstructed)

功能：该程序用于论文第4章仿真Weibull分布的海杂波。参考文献：罗军辉.《MATLAB 7.0在数字信号处理中的应用》. 电子工业出版社,p174-176. 输入：信干噪比、采样频率、尺度参数、波形参数输出：海杂波的时域和概率密度图(Features: The program for the thesis, Chapter 4 Simulation of Weibull distribution of sea clutter. References: Luo Junhui. " MATLAB 7.0 in Digital Signal Processing." Electronics Industry Publishing House, p174-176. Input: SINR, the sampling frequency, scale parameters, the output waveform parameters: sea clutter and time-domain probability density)

KL变换主分量分析 用于各种信号的处理包括图像信息的分析压缩等等(KL transform principal component analysis for a variety of signal processing, including image compression, and so the analysis of information)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
