用于模拟通信系统中不同统计信道场景下的服从不同分布的噪声。(Communication systems used to simulate different scenarios of statistical channel obey different distributions of noise.)

主要用于计算目标前向、侧向、后向散射特征，同时完成RCS极坐标图的绘制(Used to calculate the target forward, sideways, backward scattering, and complete the drawing of the polar diagram RCS)

This tests the new String object method: concat.

本去噪程序包，包含了多种小波阈值去噪算法，包含了小波变换算法的具体实现，去噪算法的具体实现，提供了一个统一的界面，便于初学者学习(this denoise package,includes servel kinds of denoise method that based on threshlod,and it has detail realization of wavelet transform,denoise method,GUI.it is convevient for beginners)

本人编写的BPAmatlab程序，用于神经网络学习。(I prepared BPAmatlab procedures for neural network learning.)

基于matlab的数字音效处理器，具有语者识别，八段数字均衡器(Matlab-based digital audio processor with speaker identification, eight digital equalizer)

(1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。 ((1) in certain wireless channel, the Doppler frequency shift will be caused by wireless channel output signal aliasing. Please describe the resulting aliasing of a variety of reasons (2) wireless channel Doppler spectrum there is a classical spectrum (classic spectrum), please explain such a spectral shape of the mechanism (3) Please use Simulink tools for writing code ( S-Function mode), resulting in a single Path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And please answer: prove that they used computer-generated classical spectrum is correct possible ways.)
