Abstract

Se proporcionan métodos y aparatos para identificar los puntos máximos correctos en salidas de filtros igualados en un equipo del usuario para sistemas de comunicación. Una señal recibida se correlaciona con una replica de una señal de sincronización, produciendo así una señal de salida de correlación. Se detectan los puntos máximos en la señal de salida de correlación. El punto máximo se prueba en una pluralidad de ubicaciones predeterminadas que se basan en propiedades de la señal de sincronización, produciendo así una pluralidad de señales de prueba del punto máximo. Se determina el máximo de las señales de prueba del punto máximo.
