Abstract

"UNIDADE DE COMUNICAçõES DE RáDIO". Em uma unidade de comunicações de rádio com vários transceptores se comunicando em bandas de freq³ência diferentes, um parâmetro de sinal de um canal selecionado é monitorado para detectar interferência devido a produtos de intermodulação. O canal selecionado é por exemplo usado por uma ligação de comunicações de rádio de longo alcance e o canal interferente em uma ligação de rádio de curto alcance. Uma vez que o canal que causa interferência foi identificado, transmissões nele são evitadas.
