Вопросы измерения и оценки параметров сигналов радиопередающих устройств систем цифровых связи

Вопросы измерения и оценки параметров сигналов радиопередающих устройств систем цифровых связи

Abstract

Проведен краткий обзор необходимых условий для обеспечения устойчивой передачи данных. Проанализированы алгоритмы обработки сигналов, которые основываются на классической теории приема сигналов на фоне аддитивного гауссовского шума без учета априорной неопределенности характеристик сигнала и помех. Предлагается построение СВЧ измерительных аттенюаторов высокого уровня мощности, которые обеспечат постоянное значение вносимого ослабления в широкой полосе частот с заданным уровнем неравномерности. Показано, что применение диплексеров на взаимодополняющих фильтрах нижних и верхних частот позволяет реализовать амплитудно-частотный корректор, согласованный в широкой полосе рабочих частот.
