无线电通信正交频移键控调制解调程序源码，给出输入数字信息序列，经调制后得到解调结果(QPSK for wireless electronic communication)

正弦波的LP建模 能显示原正弦波波形及它的频谱图，LP模型的频谱图，LP模型的极点图，LP模型的脉冲响应图。(This demonstration illustrates the modelling of a sinewave with an LP model The displays show the sinewave,it spectrum, the spectrum of the LP model,the poles of the LP model and the impuse response of the LP model.)

Root-mean-square error and mean-square signal-to-noise ratio F(x,y) the original image , F’(x,y) the decompressed image , the original image change to JPG and then JPG change to Im. Observe to Error- ratio.

by ankush laddha。This system is active front end rectifier. It keeps the DC link at reference value, 400V in this case, even if load is suddenly changes. Also power factor is controllable so can act as STATCOM too. Control is based on synchronous frame theory and 2-level inverter is switched using Sine triangle PWM technique.(This system is active front end rectifier.
