Abstract

"SISTEMA INCLUINDO UM RECEPTOR PARA RECEBER UM SINAL CONTENDO VETORES DE CóDIGOS RECEBIDOS E UM DECODIFICADOR PARA RECUPERAR ELEMENTOS DE DADOS A PARTIR DOS VETORES DE CóDIGOS RECEBIDOS". Um receptor recebe um sinal que contém um vetor de código. O vetor d código é um membro de um conjunto predeterminado de vetores de código. Os vetores de códigos pode ser vetores de códigos de Kerdock. O receptor produz uma transformada, tal como uma transformada de Walsh, do sinal recebido. A transformada contém um coeficiente correspondendo a cada um de pelo menos alguns dos vetores de códigos do conjunto predeterminado de vetores de códigos. O receptor determina elementos de dados transmitidos como o vetor de código recebido com base nas magnitudes dos coeficientes da transformada. Quando vários vetores de códigos são transmitidos, o receptor determina elementos de dados transmitidos como um primeiro vetor de código com base nas magnitudes dos coeficientes da transformada, subtrai o primeiro vetor de código a partir do sinal recebido, produz uma nova transformada dos resultados de subtração, e determina elementos de dados transmitidos como outro vetor de código com base nas magnitudes dos coeficientes da nova transformada, e assim por diante.
