Volterra analysis of spectral regrowth
TLDR
In this article, the authors present an analysis of the broadening of the bandwidth of narrowband modulated signals, commonly called spectral regrowth, caused by weak nonlinearities using Volterra methods and operating entirely in the frequency domain.Abstract:
The author presents an analysis of the broadening of the bandwidth of narrowband modulated signals, commonly called spectral regrowth, caused by weak nonlinearities. The analysis uses Volterra methods and operates entirely in the frequency domain. It is applicable to signals having either discrete or continuous spectra.read more
