Abstract

"DISPOSITIVO PARA MELHORAR UMA PROPRIEDADE DEFINIDA DE SìMBOLOS DE DOMìNIO DE TRANSFORMAçãO E RECEPTOR PARA A RECEPçãO DE BLOCOS DE SìMBOLOS PERTURBADOS". Um sistema, dispositivo e processo para melhorar uma propriedade definida de sistemas de domínio de transformação; o dispositivo inclui: um mapeador de sinais (23) que mapeia os dados de entrada em blocos de símbolos em um primeiro domínio e que gera bits de deslocamento correspondendo a cada bloco de símbolos; e um dispositivo de perturbação/transformação (27) em resposta aos blocos de símbolos no primeiro domínio e aos bits de deslocamento correspondente, o que produz blocos de símbolos de domínio de transformação perturbados a fim de melhorar a propriedade definida dos símbolos transformados.
