Abstract

"SISTEMA E MéTODO PARA FACILITAR A DEMODULAçãO DE CANAL DE PAGING RAPIDO EM UM SISTEMA DE COMUNICAçõES SEM FIO". Um sistema para facilitar a detecção e decodificação bem sucedidas de um canal de rádio localização rápida adaptado para uso com um sistema de comunicações sem fio (10) suportando um canal de rádio localização primária e um canal de rádio localização rápida. O sistema inclui um primeiro mecanismo (46, 48, 50) para detectar um sinal piloto associado com o canal de rádio localização rápida com base em um sinalo recebido e inclui um integrador coerente (104, 106) de um primeiro comprimento (N) e um integrador não coerente (114) de um segundo comprimento (m) . O segundo mecanismo determina as características operacionais do receptor do sistema com base no sinal piloto e um sinal de canal de rádio localização rápida associado com o canal de rádio localização rápida. O terceiro mecanismo otimiza o primeiro comprimento e o segundo comprimento com base nas características operacionais do receptor.
