Abstract

"PROCESSO E SISTEMA DE RECEPçãO DE UM SINAL DE BANDA ULTRALARGA. A presente invenção trata de um processo e de um sistema de recepção de um sinal banda ultralarga com número de trajetos de propagação auto-adaptativo. O sinal transmitido que comporta, em um tempo símbolo (T~ s~), uma seq³ência de impulsos diretos sucessivos modulados (IDij0) que se propaga segundo um trajeto de propagação direto e impulsos secundários (IDijk, k > 0) associados a cada impulso direto, que se propagam cada um em um trajeto de propagação secundário, o processo consiste em receber (A) a seq³ência de impulsos diretos e secundários em um mesmo circuito de recepção, em gerar (B) um motivo de correlação compósita {MCC~ ijk~} k=N/k=0 seq³ência de motivos elementares, defasados no tempo em relação a um primeiro motivo de correlação elementar, em calcular (C) o valor do coeficiente de intercorrelação global (GCC) entre cada impulso direto associado à pluralidade de impulsos secundários e o motivo de correlação compósita, para obter um valor de correlação global do símbolo, soma dos coeficientes de intercorrelação de cada um dos impulsos direto e secundários. Aplicação à ligação rádio UWB de aparelhos profissionais ou domésticos.
