Abstract

<B>MéTODO DE QUANTIFICAçãO PARA DECODIFICADOR ITERATIVO EM UM SISTEMA DE COMUNICAçãO<D> Um método de quantificação para um decodificador iterativo. No método de quantificação, os níveis de sinais recebidos são divididos igualmente a intervalos predeterminados dentro de uma faixa de 2^ n^ (n é uma integral positiva) vezes maior do que a faixa de nível de sinal de transmissão do transmissor, e o nível do sinal de entrada recebido em cada período é quantificado.
