Abstract

Se proveen un método, aparato y receptor para detectar la distorsión de intermodulación (IMD) que afecta una señal recibida en un receptor inalámbrico. Un método incluye determinar una medición indicativa de la IMD en base al menos a una señal de transmisión. Cuando la medición indicativa de IMD excede un primer nivel predeterminado, el receptor inalámbrico recoge al menos una muestra de una amplitud de una salida de señal en un primer conjunto de datos. Cuando la medición indicativa de distorsión de intermodulación no excede un segundo nivel predeterminado, siendo el segundo nivel predeterminado menor que el primer nivel predeterminado, el receptor inalámbrica recoge al menos una muestra de una amplitud de la salida de señal en un segundo conjunto de datos. Se efectúa una comparación en base a datos del primer conjunto de datos y datos del segundo conjunto de datos para determinar una medida de la IMD.
