Abstract
A method of detecting a received signal, includes determining correlation between a received signal in a predetermined signal interval and training symbols, and determining a median absolute deviation (MAD) of the received signal in a predetermined reference interval. The method further includes detecting a presence of the received signal based on the correlation and the MAD.
Claims18
A method of detecting a received signal, the method comprising:
- determining correlation between a wireless received signal in a predetermined signal interval and training symbols;
- determining a median absolute deviation (MAD) of the wireless received signal in a predetermined reference interval;
- and
- detecting a presence of the wireless received signal based on the correlation and the MAD.
A device that detects a received signal, the device comprising:
- a correlator configured to determine correlation between a received signal in a predetermined signal interval and training symbols;
- a median absolute deviation (MAD) determining unit configured to determine an MAD of the received signal in a predetermined reference interval;
- and
- a detecting unit configured to detect a presence of the received signal based on the correlation and the MAD.
