FFT

是一个常规PID控制例子(包括了系统建模部分),控制对象为直升机的俯仰轴角度控制,其数学模型为二阶传递函数.(Is an example of conventional PID control (including the system modeling part), control for the helicopter pitch angle control axis, the mathematical model for the second-order transfer function.)

matlab code for communication

说明：  主要实现基于LMS算法的自适应滤波器,基于自适应算法的信号增强(Adaptive filter based on LMS)

粒子与卡尔曼滤波程序，用来机动目标跟踪数据的滤波和分析(Particle and Kalman filtering program used to analyze maneuvering target tracking)

产生一组简单的线性调频chirp信号,帮助大家学习matlab 用于雷达脉冲压缩(creat a simple LFM signal)

说明：  香农、费诺、霍夫曼编码以及费诺不等式的相关代码(Shannon, FeNO, Hoffman code)

单脉冲信号、调频信号模糊函数源代码，很实用！(Single-pulse signal, FM signal ambiguity function source code, it works!)

FTCS, FTFS and FTBS program to analysis of square and sinusoidal wave eqn

matlab仿真PSK的一个doc文档，有显示波形图，等等，是个完整的程序，比较长比较完整的，可以选择性使用(matlab simulation of PSK, a doc document showing the waveform, etc., is a complete program, the longer more complete, you can selectively use)
