In this thesis, the problem of spectrum sensing in cognitive radio communication networks
is considered. This thesis has developed a robust decision fusion scheme that can perform
well when the interference caused by other PUs is present. Specifically, the proposed detection
scheme is based on fusing the local decisions from energy detectors (EDs) and cyclostationarity-
based detectors (CDs). Our proposed fusion scheme is different from other power spectrum
sensing technology being developed so far in that other fusion technology are based on fusing
the local decisions from the same type of detectors. Our proposed fusion scheme can take the
advantage of both EDs and CDs. We compare the proposed scheme with the schemes fusing
the same type of detectors, and the results confirm that the proposed scheme is more robust
against the possible interference.
