METHOD AND DEVICE FOR QUASICOHERENT RECEPTION OF MULTIBEAM SIGNAL AND SINGLE-BEAM QUASICOHERENT RECEIVER SIGNAL PROCESSING UNIT

摘要

FIELD: radio engineering; radio receivers of base and mobile stations. SUBSTANCE: Invention is based on assumption that statistical dependence of complex useful-signal envelope is of linear character. Use is made of interpolation or prediction of complex waveform envelope by means of method of least squares. Data characters used for carrier recovery essentially raises multibeam signal reception characteristics at negligible complication of processing. EFFECT: enhanced noise immunity in receiving signals with chopped pilot signal at different data transfer speeds and channel statistics with enhanced throughput of system. 8 cl, 10 dwg
