Generate 4QAM sistem

RLS源程序代码，方便学习和使用改进的最小二乘法，加以修改，随心所欲！(RLS source code, easy to learn and use to improve the least squares method, modify, anywhere!)

false nearest neighbor calculation on a signal as a chaotic indicator

MATLAB实现ASK调制解调。 内含主文件、demo文件，高斯噪声文件等等。(MATLAB ASK modulation and demodulation.)

基于模拟电荷法求解导线周围空间的空间电场(Solving the electric field around the wire based on space charge simulation method)

People can use this to build a MATLAB project for LQR control

求三阶传递函数的阶跃响应 其中对象采样时间为1ms。 采用专家PID设计控制器。在仿真过程中， 取0.001，程序中的五条规则与控制算法的五种情况相对应。 (Seeking third-order transfer function of the step response in which the object sampling time 1ms. PID controller is designed by experts. In the simulation process, taking 0.001, five rules and procedures in the control algorithm corresponding to the five conditions.)

说明：  一个ga的matlab源程序，读懂它可以方便地处理问题。(ga matlab procedure，read it you can deal with your problem easily)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

用matlab做图像处理的代码，主要是用函数处理图像(Image processing code)
