Abstract
A method for detecting a false detection of a packet. The method includes generating a frequency domain representation of a signal, the frequency domain representation including a plurality of complex values each of which is associated with a subcarrier. The method also includes determining an angle for each of the subcarriers, and determining for each pair of adjacent subcarriers an angle difference. The method then includes accumulating the angle differences to produce an accumulated angle, and detecting the false detection based upon the accumulated angle.
