Abstract

"MéTODO E EQUIPAMENTO PARA CONTROLE DE POTêNCIA EM UM SISTEMA DE COMUNICAçãO SEM FIO". Em um sistema de comunicação sem fio (10) possuindo um canal de transporte composto constituído por canais de transporte individuais, um método para controle de potência em malha fechada em que múltiplos casos do loop externo são efetuados em paralelo. O método determina um limite de relação de sinal para interferência (SIR) para o canal composto com base em uma métrica de qualidade de canal avaliada para cada um dos canais individuais. Em uma modalidade, a métrica de qualidade de canal é um resultado da verificação de redundância cíclica (CRC).
