On limit efficiency of SW radio interference compensation in spatial signal processing

Radiophysics and Quantum Electronics Aims and scope

Abstract

The possibilities of interference compensation have been experimentally studied for spatial signal processing in a nonstationary SW communication channel. It is shown that the mean efficiency of interference suppression by correlation methods is about 20 dB for quasimonochromatic interference and 12 dB for frequency-manipulated interference. The multipathing and dispersion of the communication channel are analyzed as the main causes limiting the characteristics of SW interference compensators. An empirical model of the channel has been proposed to explain the observed SW signal characteristics.
