Abstract

Es posible utilizar un dispositivo de estación de base empleado en un sistema de comunicación móvil que incluye una pluralidad de celdas que tiene una pluralidad de sectores. El dispositivo de estación de base incluye: el medio que genera un canal de sincronización utilizado para la búsqueda de celda a través de un dispositivo de usuario; y el medio de transmisión de radio de una señal que contiene el canal de sincronización. El canal de sincronización tiene un canal primario de sincronización y un canal secundario de sincronización. El canal primario de sincronización tiene una pluralidad de tipos de secuencias. El canal secundario de sincronización que es transmitido en un cierto sector de una cierta celda contiene un código derivado partir de un polinomio predefinido de generación que corresponde con el canal primario de sincronización.
