Abstract

Cada trama de una transmision en un sistema de comunicaciones de espectro ampliado se divide en multiples ranuras de sincronizacion. Cada una de lasranuras de sincronizacion incluye un codigo de piloto y, por lo menos una de las ranuras desincroniza cion, incluye además un codigo de sincronizacion detramas. Para extraer informacion sobre sincronizacion de trama y ranura en la transmision del canal de piloto, la puesta a tiempo del codigo de piloto seidentifica primero aplicando unfiltro coincid ente o correlacion a una senal de piloto recibida, identificando picos y usando los picos para hallar unareferencia de puesta a tiempo indicativa de los límites de ranuras de sincronizacion. A continuacion, el conjunto de codigos desincronizacion de tramasconocidos se correlacionan con la senal recibida a través de las ranuras de sincronizacion halladas incluidas. Dado que se conoce la localizacion dentro de latrama del (de los) codigo(s) de sincronizacion de tramas, una vezhallada una coincid encia de correlacion en una cierta localizacion de ranura, también seconoce el límite de la trama (es decir, la sincronizacion de la trama) relativa al (a los) mismo(s).
