SU1840195A1 - Broadband communication device - Google Patents

Abstract

FIELD: radio engineering, possible use in asynchronous-address communication systems with code division of channels.SUBSTANCE: broadband radio communication device contains, in transmitter - generator of bearing and clock frequencies, adder, connected serially, first generator of orthogonal pseudo-random series and first multiplexer, connected serially, first generator of pseudo-random series and second multiplexer, phase shifter for 90°, phase manipulator, first phasing block; in receiver - synchronization block, phase detector, connected serially, second generator of orthogonal pseudo-random series, third multiplexer and first band filter, connected serially, second generator of pseudo-random series, fourth multiplexer and second band filter, second phasing block; transmitter additionally contains first phase manipulator for 90° and first generator of additional series; and receiver additionally contains, connected serially, first broadband filter, limiter, subtraction block and second broadband filter, and also second and third phase manipulators for 90°, second generator of additional series, two additional multiplexers, two additional band filters, comparison block, additional phase detector and commutator.EFFECT: increased interference resistance of communication system.2 dwg
