Abstract
Изобретение относитс к технике радиосв зи и может испльзоватьс при построении приемников систем передачи информации по тропосферным радиоканалам крайневысокочастотного диапазона. Цель изобретени вл етс повышение помехоустойчивости приема миллиметровых радиоволн в дисперсионных тропосферных каналах с частотно-селективными замирани ми. Устройство содержит анализатор 1, блок 2 восстановлени несущей частоты, фильтр 3, два коммутатора 4, 6, блок 5 задержки, перемножитель 7, блок 8 тактовой синхронизации и решающий блок 9. Анализатор содержит два полосовых фильтра, два ограничител уровн , два перемножител , два интегратора, блок вычитани и пиковый детектор. 1 з.п. ф-лы, 2 ил.The invention relates to a radio communication technique and may be used in the construction of receivers of information transmission systems over the tropospheric radio channels of the extreme high frequency range. The purpose of the invention is to improve the noise immunity of reception of millimeter radio waves in dispersive tropospheric channels with frequency selective fading. The device contains an analyzer 1, a block 2 of carrier frequency, a filter 3, two switches 4, 6, a delay block 5, a multiplier 7, a clock synchronization block 8, and a decisive block 9. The analyzer contains two bandpass filters, two level limiters, two multipliers, two integrator, subtraction unit and peak detector. 1 hp f-ly, 2 ill.
