通信系统仿真原理与无线应用，很好的一本关于通信系统仿真的书(Principles of Communication System Simulation and wireless applications, a good book on the communication system simulation)

说明：  文主要目的是针对讯号频谱分析仪(Signal spectrum analyzer)做功能测试，以确定讯号频谱分析仪之各种运算功能正确，其中测试共 分为正弦与余弦波检查、反假象滤波器检查(Antialiasing Filter Check)、频率响应函数与相位角检查(FRF & Phase Check)、自身能量密度函 数检查(Power Spectrum Check)、动态范围检查(Dynamic Range Check)等五个项目的快速傅立叶转换检查(Fast Fourier Transform Check)，并 对五个项目之测试原理、测试步骤及测试结果加以说明，提供频谱分析仪功能测试之正确方法，亦可作为自制频谱信号处理单元及频谱分 析程式之验证。(The main purpose of the text is for the signal spectrum analyzer (Signal spectrum analyzer) to do functional testing, to determine the signal spectrum analyzer features a variety of computing the right, which is divided into sine and cosine test wave inspection, anti-false filter inspection (Antialiasing Filter Check), the frequency response function and phase angle of inspection (FRF &amp Phase Check), its energy density function check (Power Spectrum Check), dynamic range checking (Dynamic Range Check) and other five projects FFT check (Fast Fourier Transform Check ), and principles of the five test items, test steps and test results to show that the spectrum analyzer to provide the proper testing method may be used as self-spectrum signal processing unit and the spectral analysis of the verification.)

数学公式模型的仿真，在matlab环境下把数学公式的图像画出来(Math model simulation, in the matlab environment, the mathematical formulas drawn images)

软件工程的设计和开发文件，由于本人也不知道怎么回事，所以还请读者自己去斟酌，希望对你们有帮助！(software engineering design and development, because I do not know how, therefore, also invited readers to their own discretion, and I hope to have your help!)

this is the another matlab code for gui signals

说明：  蚁群算法研究 Ant colony algorithm(Ant colony algorithm. Txt)

说明：  无刷双馈电机模型，开环仿真总是出错，希望大家帮帮忙看看啊(BDFM model, open-loop simulation is always wrong, hope that we help out and take a look at ah)

说明：  用选主元的Gauss-Jordan方法计算矩阵的逆矩阵 matlab(With pivoting Gauss-Jordan method of inverse matrix matlab)

基于多尺度的小波边缘检测的matlab的代码，含有去噪算法(Edge detection based on wavelet multiscale matlab code, containing de-noising algorithm)

说明：  最速下降法matlab源码 有一定参考价值(Steepest descent method matlab source has certain reference value)
