MULTICHANNEL RECEIVER WITH COHERENT FREQUENCY-CODE DIVISION OF CHANNELS FOR RECEPTION OF QUADRATURE-MODULATED SIGNALS OF HIGHER STRUCTURAL SECURITY

摘要

FIELD: radio engineering and communication.;SUBSTANCE: invention relates to radio communication and can be used in wireless access systems, land mobile and satellite communication, designed to operate in conditions of restrictions on dedicated frequency resource. Multichannel receiver with coherent frequency-code division of channels for receiving quadrature-modulated signals of high structural security includes a coherent frequency grid generator, main receiving module, M additional receiving modules, as well as corresponding connections between them.;EFFECT: technical result consists in possibility of reliable reception of high structural concealment signals and high spectral efficiency of allocated frequency spectrum.;1 cl, 5 dwg
