基2 fft 的c++实现，改自matlab。(fft)

说明：  Matlab在数字信号处理的应用,xju的教学ppt,很不错.(Matlab in digital signal processing applications, xju teaching ppt, very good.)

研究了基于信号强度模型的室内定位技术. 通过运用线性回归、补偿式线性回归和多元回归方法，利用 仿真数据建立了信号强度模型.(Indoor positioning technology based on signal strength model by using linear regression, the compensated linear regression and multiple regression method using simulation data signal strength model.)

基于Matlab的数字通信原理，介绍了各种通信方式的原理和相应的Matlab编程，是学习数字通信原理的绝好材料。 (Digital Communication Principle in Matlab for students and engineers is very good conference.)

在matlab下进行滑模变结构控制仿真系统的研究。希望对研究控制的同志有帮助。本人做论文时写的(Matlab under the sliding mode variable structure control simulation system. I hope the study will help control comrades. I used to do paper)

svPWM仿真，光伏逆变svpwm仿真，simulink仿真(SvPWM simulation, photovoltaic inverter SVPWM simulation, Simulink simulation)

实验一 Matlab使用及离散时间傅立叶变换 实验二应用傅立叶变换对信号进行频谱分析 实验三 数字滤波器的设计 (Experiments using Matlab and a discrete-time Fourier transform second experiment the signal Fourier transform spectrum analysis experiment three digital filter design )

用牛顿法解决非线性规划问题，解决问题所需时间少，能提高效率，但须具有二阶导数(Newton' s method to solve nonlinear programming problems, less time, and can improve the efficiency needed to solve the problem, but must have a second derivative)

用于雷达阵列信号的处理，比较经典的music算法，对大家会有帮助的(Used in radar array signal processing, algorithms with classical music, will be helpful to everyone)

现代谱估计中，ar模型与arma模型的比较，性能的区别(Modern spectral estimation, ar arma model model and compare the difference between the performance)
