Abstract

Métodos y aparatos en un receptor para estimar una potencia recibida de por lo menos una señal que tiene un patrón conocido por el receptor, la señal se ha transmitido por al menos una antena. Un método incluye utilizar un primer método para medir la potencia recibida basándose en el patrón, el primer método genera una primera secuencia de primeras estimaciones de potencia; determinar si un primer evento predeterminado ha ocurrido; y si el primer evento ha ocurrido, cambiarse a un segundo método para medir la potencia recibida, el segundo método es diferente del primer método y genera una segunda secuencia de segundas estimaciones de potencia.
