Abstract
A white space sensing method includes measuring a peak to average power ratio (PAPR) of a signal of a channel in a spectrum band. The method also includes determining whether a ratio of the measured PAPR to a predetermined PAPR of a modulation scheme associated with the signal meets a predetermined threshold. The method further includes indicating the channel is available for use by an unlicensed user when the ratio meets the predetermined threshold.
