Different types of digitally modulated signals that have similar, if not identical, powerspectraldensity functions can have highly distinct spectral correlation functions.
一些不同的数字调制信号有着相同或相近的功率谱密度,但它们的谱相关函数却有明显区别。

The experimental results of the different aperture parameters and the powerspectraldensity of wavefront slope are derived in the paper.
本文推导了采用不同孔径参数的实验结果,以及波前斜率的功率谱密度。

But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of powerspectraldensity of the reference signal.
