Abstract

"CONTROLE DE MARGEM DE POTêNCIA EM UM SISTEMA DE COMUNICAçãO DE DADOS". São descritas técnicas para melhor controle de margem em um sistema de comunicaçao de dados. Em um aspecto, a margem é ajustada em resposta a uma primeira taxa de erros de subpacotes (350). Em mais outro aspecto, a primeira taxa de erros de subpacotes é ajustada em resposta a uma taxa de erros de pacotes total (350) . Vários outros aspectos são também apresentados. Tais aspectos apresentam o benefício de controle de margem reativo quando a taxa de erros de pacotes total é relativamente baixa, resultando em melhor capacidade de transmissão de dados e maior capacidade do sistema.
