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.
