Abstract

Для ретрансляции канала связи на определенной частоте приемник (100) принимает сигнал, имеющий определенную частоту канала связи. Аналогово-цифровой преобразователь (130) генерирует цифровой сигнал, скоррелированный с принятым сигналом, и цифровой сигнал пропускают через цифровой фильтр (140), сконфигурированный для фильтрации цифрового сигнала и пропускания частотных компонентов на определенной частоте канала связи или вокруг нее. Цифроаналоговый преобразователь (150) генерирует аналоговый сигнал, скоррелированный с отфильтрованным цифровым сигналом, и передатчик передает аналоговый сигнал.Отчет о международном поиске был опубликован 2004.03.04.
