Abstract

Based on the coherency function properties, a new method for estimating the power spectral density of an information signal in the presence of lumped interference is suggested. The paper includes results of instrumental calculation of articulation characteristics when reception of signals with single-band modulation occurs in the presence of lumped interference modulated in phase by Gaussian random process.
