Abstract

APARELHO TRANSMISSOR DE RáDIO, APARELHO RECEPTOR DE RáDIO, E SISTEMA DE COMUNICAçãO SEM FIO. A invenção refere-se a um sistema de comunicação sem fio capaz de obter um ganho de diversidade sem falhar mesmo quando a distribuição das qualidades de recepção é grande. Em um aparelho de transmissão de rádio (100) do sistema de comunicação sem fio, uma parte de decisão de razão de repetição/ padrão de constelação (113) ajusta o número de constelações a serem utilizadas por uma parte de modulação (102) e também ajusta o número de réplicas de uma parte de repetição (103) de tal modo que o produto do número de padrões de constelação a serem utilizadas pela parte de modulação (102), isto é, o número de símbolos de saída a serem gerados e o número de símbolos de saída como replicados pela parte de repetição (103) tornam-se iguais ao número de símbolos de saída gerados de um único dado de transmissão notificado de uma parte de extração de informações de controle (112).
