METHOD AND DEVICE FOR QUASI-COHERENT RECEPTION OF MULTIBEAM SIGNAL

摘要

FIELD: radio engineering; receiving cluster-structure multibeam signal in code-division communication systems.;SUBSTANCE: among methods for correct evaluation of complex beam waveform envelope taking into account mutual influence of beam signals is generation of decorrelated response of pilot symbols used for shaping estimates of complex envelope of information symbols. Decorrelated responses can be shaped by weighted addition of complex correlation responses of beam-signal pilot symbols, weighting coefficients being generated in the form of column constituents of matrix reverse to cross-correlation matrix depending on relative time positions of multibeam signal components and also on signal spectrum.;EFFECT: enhanced noise immunity in receiving cluster-structure multibeam signal.;4 cl, 5 dwg
