Abstract

(57) Для определения рабочей точки нелинейного усилителя (2) канала связи (1), например ретранслятора в спутнике связи, через канал связи (1) передается первый входной сигнал (I) с уровнем мощности (P), который возбуждает нелинейный усилитель (2) в нелинейном режиме работы. Кроме того, второй входной сигнал (i) передается через канал связи CD одновременно с первым входным сигналом (I). Второй входной сигнал (i) передается с уровнем ниже уровня первого входного сигнала (I). Если доля второго входного сигнала (i) в суммарный входной сигнал нелинейного усилителя мала, рабочая точка нелинейного усилителя определяется почти исключительно первым входным сигналом. Поэтому выходная мощность (P), соответствующая второму сигналу (i), определяется наиболее точно входной мощностью (P) первого сигнала (I). Рабочая точка (I, P) упомянутого нелинейного усилителя (2) определяется на основании выходного сигнала (o) упомянутого канала связи (1), соответствующего упомянутому второму сигналу (i).Международная заявка была опубликована вместе с отчетом о международном поиске.
