SYSTEM AND METHOD FOR SELECTIVE CHANNEL REMOVAL IN MULTI-CHANNEL RECEIVERS

摘要

The present invention is related to a method for detecting a transmitted wake-up signal in a wireless communication system comprising a plurality of communication nodes. The method comprises the steps of : - receiving at a communication node of said plurality a transmitted wake-up signal, said wake-up signal being split over a plurality of frequency channels and a plurality of time slots, - determining per frequency channel an indication of the signal quality on that frequency channel, - deciding per frequency channel on removing the signal portion corresponding to that frequency channel, based on the indication of the signal quality, thereby obtaining a reduced received wake-up signal, - correlating the reduced received wake-up signal with a version of a local copy of the transmitted wake-up signal, - detecting the transmitted wake-up signal from the result of the correlation step.
