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.

A method of spectrum sensing, the method comprising:
- 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.
An apparatus for performing spectrum sensing, the apparatus comprising:
- a processor configured to partition a spectrum sensing section partitioned into a plurality of sub-periods each having a same size, and to determine presence of a primary user's signal 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.
