Abstract

PROCESSAMENTO DE SINAL DE INFORMAçõES PELA MODIFICAçãO DA REPRESENTAçãO DA FAIXA ESPECTRAL/ESPECTRAL DE MODULAçãO. O processamento de sinais de informações separados de acordo com a modulação e componentes portadoras de maneira mais controlada é possibilitado por um dispositivo de processamento de um sinal de informações (14) incluindo um meio (20) para a conversão do sinal de informações (14) em uma representação tempo/espectral pela transformação em bloco do sinal de informações e o meio (22) para a conversão do sinal de informações da representação tempo/espectral para uma representação espectral/espectral de modulação, caracterizado pelo fato de que o meio (22) para a conversão é desenhado de maneira que a representação espectral/espectral de modulação dependa tanto de uma componente de magnitude como de uma componente de fase da representação tempo/espectral do sinal de informações (14). Um meio (24, 40) faz então uma manipulação e/ou modificação do sinal de informações (14) na representação espectral/espectral de modulação para obter uma representação espectral/espectral de modulação modificada. Um outro meio (26) finalmente forma um sinal de informações processado (18) que representa uma versão processada do sinal de informações (14) baseado na representação espectral/espectral de modulação modificada.
