Power Spectral Density of Interference Caused by Nonlinear Distortions in Devices with Amplitude-Phase Conversion

摘要

A technique for estimating the spectrum in the basic band of interference arising in noninertial nonlinear devices with amplitude-to-phase conversion, which makes it possible to estimate the signal-to-interference ratio in this band and, therefore, assign the maximum intensity of the given devices, is proposed. This technique is exemplified by considering the digital transmission systems based on the orthogonal frequency-division multiplexing technology and the power amplifiers of base and mobile stations of cellular and wireless access systems.
