Abstract

"APARELHO E MéTODO PARA DETECTAR UMA TAXA DE TRANSMISSãO DE UM TURBO DECODIFICADOR". A presente invenção refere-se a um aparelho e método para detectar uma taxa de dados em um turbo decodificador para um sistema móvel de comunicações. Quando um seletor de taxa de dados seleciona uma taxa de dados dentre diversas taxas de dados, um turbo decodificador decodifica repetidamente um quadro de dados de entrada dentro de um número limite de repetições predeterminado mediante utilização da taxa de dados selecionada e envia os dados decodificados. Um detector CRC realiza verificação CRC nos dados decodificados e envia o resultado da verificação CRC, e um medidor de estado de decodificação mede a qualidade de decodificação que depende dos dados decodificados e envia informações sobre estado de decodificação. Um controlador ajusta em seguida o número limite de repetições para um valor mínimo predeterminado, controla o número limite de repetições de acordo com as informações sobre estado de decodificação, controla o seletor de taxa e determina uma taxa de dados dos dados de entrada dependendo do resultado da verificação CRC.
