Phase Locked Loop simulation

此算法是基于PN序列的经典的定时同步算法，能直接出图，望对大家有用(This algorithm is based on the classic PN sequence timing synchronization algorithms, directly out of maps, useful look on the U.S.)

基于Matlab的一种光伏阵列模拟器的研究(matlab)

本书是非常不错的信号检测与估计的书籍！值得一看！(fundamentals of stastic signal processing!)

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others
