说明：  倒立摆-采用LQR（线性二次型最优控制）方法实现倒立摆控制(inverted pendulum-use LQR (linear quadratic optimal control) method inverted pendulum control)

这是一个用matalb语言实现的FIR滤波器的源代码，直接可以运行，已经经过本人调试通过，对于信号处理的同行有帮助。(this is a matlab program that compute the fir filter and it was been tested by myself.)

由david vallado更新的轨道确定的程序代码，本程序融合sgp4和sdp4，包含193个文档(this procedure is the sgp4 prediction model from space command. this is an updated and combined version of sgp4 and sdp4)

matlab写的实现不同信号之间采样，卷积，重构等。里面有一个.exe是用matlab写的界面，可以打开看到效果。(matlab written between the different signals sampling, convolution and reconstruction. There is one. Exe matlab write interface, you can open to see the effect.)

about fourier transform, get audio signal from mic and analyze it

在模型阶数和时滞已知与未知情况下，系统辨识与建模的5种最小二乘法。(5 kinds of least square method for system identification and modeling in the model order and time delay are known and unknown.)

说明：  关于ofdm建模的Matlab程序，可以实现ofdm系统性能仿真(Matlab on ofdm modeling procedures, system performance can be achieved simulation ofdm)

说明：  微波系统的模型，使用matlab gui 界面实现(Microwave system model, using matlab gui interface implementation)
