Abstract
A wake-up method for a multi-channel receiver comprises the following steps: checking for activity on every available channel by switching from one channel to the next thereby activating and subsequently deactivating one channel after the other; when activity is detected at least on one of the available channels, switching on all channels, measuring a respective received signal strength in every channel and performing a comparison of received signal strengths between all channels; and selecting the channel with the highest received signal strength. Further a multi-channel wake-up receiver is presented.

A wake-up method for a multi-channel receiver comprising the steps of:
- checking for activity on every available channel by switching from one channel to the next thereby activating and subsequently deactivating one channel after the other;
- when activity is detected at least on one of the available channels, switching on all channels, measuring a respective received signal strength in every channel and performing a comparison of received signal strengths between all channels;
- and
- selecting the channel with the highest received signal strength.
A multi-channel wake-up receiver with several channels, each channel comprising:
- an activity detector with an input to be supplied with a carrier signal and an output to provide an activity signal;
- a signal strength measurement unit coupled to the output of the activity detector with an output to provide a received signal strength indication signal;
- and
- a comparison unit coupled to the output of each signal strength measurement unit having an output to provide a selection of the channel with the highest received signal strength.
