Abstract
Se describe una arquitectura tipo rastrillo para un sistema de comunicacion duplex con division de frecuencia (FDD) y tambien de uso en sistemas tipo TDD y TD-SCDMA, la arquitectura esta disenada para reducir significativamente la capacidad de memoria requerida, y de este modo, reducir tambien un area en el dado de un circuito integrado especifico de la aplicacion (ASIC) en el cual se integra la memoria. Una memoria intermedia circular unica (60), de manera preferente del tipo de memoria compartida, se comparte por todos los dedos del rastrillo (DEDOS DE RASTRILLO 1, 2, 3, 4, 5 Y 6) del receptor tipo rastrillo para reducir de manera significativa el equipo fisico y programas de computo requeridos para alinear en el tiempo las senales Multi-ruta (ENTRADA DE DATOS) recibidas por un UE (equipo de usuario) desde la estacion base. La tecnica unica de alineacion en el tiempo tambien reduce el numero de generadores de codigo (62, 64 y 66) requeridos para seguir una pluralidad (tipicamente tres) de estaciones base.
