Abstract

"MéTODO E EQUIPAMENTO PARA DETECçãO APROPRIADA DE ERROS DE TAXA EM RECEPTORES DE TAXA VARIáVEL". Um sistema e um método para detecção de erros de algoritmos de determinação de taxa em receptores de sistemas de comunicações de taxa variável. As modalidades descritas impedem que erros de algoritmos de determinação de taxa causem ocorrências audíveis tais como chiados ou "bips". O sistema e o método descritos detectam frames com taxas de dados incorretamente determinadas e efetuam o processamento de apagamento de frames e/ou limpeza de memória armazenada para impedir a propagação de distorções através de múltiplos frames. Os frames com taxas de dados incorretamente determinadas são detectados por verificação por transições de taxa ilegais, bits reservados, validação de combinações de bits do tipo filtro não utilizado e análise de relações entre ganhos de livro código fixo e ganhos de coeficientes de previsão linear.
