Abstract

"MéTODO PARA CONFIAVELMENTE CONTROLAR UM DISPOSITIVO DE BUSCA, SEçãO DE RECEPçãO CONTROLADA PELO MéTODO, E SISTEMA CDMA INCLUINDO A SEçãO". Em um método para controlar um dispositivo de busca usado em uma seção de recepção suprida com uma seq³ência de sinais de dados de recepção de banda base divisível em uma seq³ência de quadros, uma taxa de quadro corrente em um quadro corrente é usada para calcular a próxima taxa de quadro em um próximo quadro seguindo o quadro corrente e determinar slots candidatos no próximo quadro com referência à próxima taxa de quadro. O dispositivo de busca executa operação de busca nos slots candidatos no próximo quadro. O próximo quadro é calculado de modo que não seja maior que a taxa de quadro corrente, de modo a confiavelmente executar a operação de busca. Os slots candidatos no próximo quadro podem ser determinados por um randomizador de pacote de dados.
