Abstract

"INTERCALADORES APERFEIçOADOS PARA CóDIGO TURBO" Trata-se de sistemas e métodos para intercalar códigos que inclui um processador que atua sobre o quadro de dados recebido e armazenado em uma memória. O processador separa as partes do quadro de dados e permuta as partes, alcançando a dispersão máxima dos dados por utilizar equações baseadas na teoria numérica.
