Abstract

"APARELHO E MéTODO PARA DETERMINAR UM ESQUEMA DE MODULAçãO EM UM SISTEMA DE COMUNICAçãO". Um aparelho e método para determinar um esquema de modulação ótimo e a velocidade de código em um sistema de comunicação que utiliza um esquema de transmissão variável. Em um transmissor incluído no sistema de comunicação, o codificador codifica um pacote de codificador (EP) e uma pluralidade de moduladores tendo diferentes ordens de modulação modulam sub-pacotes sendo palavras de código emitidas do codificador. O seletor seleciona um dos moduladores ao comparar a MPR (Velocidade de código de produto de ordem de modulação) sendo uma proporção entre o tamanho do EP e o número de símbolos de modulação de carga, e comparar a MPR com o limite.
