FIELD: transmission of broadband noise-like signals. SUBSTANCE: proposed broadband radio communication system is designed for high-speed transmission of broadband noise-like signals and can be used in short-wave communication systems as well as in other communication systems where multibeam propagation of radio waves may occur. In order to enhance noise immunity when receiving signal pulses in short-wave broadband radio communication system that has n(n>=2) radio stations, each radio station is provided with newly introduced series-connected preamble detector, time interval generator, information signal detector, and multivalued code decoder, series-connected multivalued code decoder and control unit, as well as preamble generator. EFFECT: enhanced noise immunity of information signal reception. 2 cl, 8 dwg, 1 tbl |
