Abstract

MéTODO, APARELHO E SISTEMA PARA DETECTAR SINAL. Método e aparelho para detectar sinais são descritos, onde o primeiro grupo de símbolos representa o sinal no receptor. O segundo grupo de símbolos é estimado, representando o sinal transmitido no transmissor usando a técnica de decodificação esférica. A estimação pode empregar ao menos dois esquemas de modulação. A informação confiável relativa aos bits que formam um símbolo pode ser determinada para ao menos um símbolo do segundo grupo. Em adição, a informação confiável relativa ao sinal pode ser levada em conta na estimação de ao menos um símbolo do segundo grupo.
