1. A method for sensing features of a signal in a wireless communication system, the method comprising:

  • determining a plurality of spectral density estimates, each estimate of the plurality being derived based on reception of the signal by a respective antenna of a plurality of antennas;

    combining the plurality of spectral density estimates; and

    sensing the signal features based on the combination of the plurality of spectral density estimates.
