Abstract

"CONTROLE DE AJUSTE DE GANHO ADAPTATIVO COM REALIMENTAçãO". São apresentados sistemas e técnicas referentes às telecomunicações que incluem a transmissão de uma pluralidade de grupos de dados a um receptor a um primeiro nível de potência, a retransmissão de um primeiro dos grupos de dados ao receptor a um segundo nível de potência mais baixo que o primeiro nível de potência, o fornecimento de realimentação do receptor referente à retransmissão do primeiro dos grupos de dados e a retransmissão de um segundo dos grupos de dados ao receptor a um terceiro nível de potência diferente do segundo nível de potência, o terceiro nível de potência sendo uma função da realimentação.
