Abstract
"MéTODO E EQUIPAMENTO PARA CONTROLAR O NìVEL DE POTêNCIA DE SINAL EM UM SISTEMA DE COMUNICAçãO". Um método e um equipamento novos e aperfeiçoados para controlar o nível de potência de sinal em um sistema de comunicação (100) são providos pela determinação de primeira e segunda relações sinal/interferência de um sinal recebido respectivamente antes e após um cancelamento de interferência, determinação de uma diferença entre as primeira e segunda relações sinal/interferência e determinação, com base na diferença, de um limite de sinal/interferência para controle do nível de potência de um sinal transmitido a partir de uma fonte do sinal recebido.
