Abstract

"PROCESSO E EQUIPAMENTO PARA SINCRONIZAR CONJUNTOS DE DADOS PARA TRANSMISSãO ATRAVéS DE UMA PLURALIDADE DE CANAIS PARALELOS, E, PROCESSO E EQUIPAMENTO PARA SINCRONIZAR CONJUNTOS DE DADOS RECEBIDOS ATRAVéS DE UMA PLURALIDADE DE CANAIS". A presente invenção compreende um processo e equipamento para sincronizar conjuntos de dados (110) de um fluxo de dados de largura de faixa larga (100) que é dividido e transmitido através de uma pluralidade de canais paralelos (170A-P) em um sistemas de telefonia móvel. Antes de transmitir os conjuntos de dados (110), um sincronizar de transmissão (120) sincroniza os conjuntos de dados (110) alinhados na mesma posição em diferentes canais paralelos (170A-P) pela inserção de um bit comum (160) de uma seq³ência de sincronização de PN repetitiva (150) nos conjuntos de dados alinhados (110). Ao receber os conjuntos de dados (110) em um destino, um sincronizador de recepção (145) extrai o bit de sincronização (160) de cada conjunto de dados (110). Uma série de bits sequenciais (155) de cada canal paralelo é comparada com a sequência de sincronização de PN (150) para identificar a posição de cada conjunto de dados (110) relativa a outros conjuntos de dados (110) e reconstrui o fluxo de dados de largura de faixa larga original (100).
