Abstract

"MéTODO E EQUIPAMENTO PARA PERFURAR SìMBOLOS CóDIGO EM SISTEMA DE COMUNICAçõES". Trata-se de técnicas para perfurar símbolos em um sistema de comunicações. S Símbolos são recebidos por um frame que tem uma capacidade de N símbolos, com S sendo maior que N. P Símbolos precisam ser perfurados de modo que os símbolos restantes se encaixem no frame. Um número de distâncias de perfuração, de D1 até DN, são computadas com base em S e P. Um número específico de perfurações de símbolo é determinado para cada distância de perfuração computada. As perfurações de símbolo de P1 até PN são então efetuadas às distâncias de D1 até DN, respectivamente. Para uma distribuição mais uniforme das perfurações de símbolo, cada uma das distâncias de Dl até DN pode ser selecionada para ser maior ou igual a uma distância de perfuração mínima, Dmin, definida como Dmin = [S/P], onde [] denota um operador de piso. As perfurações de símbolo a cada distância computada podem ser executadas juntamente, ou distribuídas, com perfurações de símbolo a outras distâncias.
