Abstract
A method of spectrum sensing and an apparatus for spectrum sensing are provided. A method of spectrum sensing involves partitioning, by a processor, a spectrum sensing section into a plurality of sub-periods each having a same size, performing energy detection in each of the plurality of sub-periods, and determining whether a primary user's signal is present in the spectrum sensing section based on presence of a primary user's signal in each of the plurality of sub-periods and a test statistic in each of the plurality of sub-periods.
