- This paper proposes a hybrid double-threshold based energy detector (HDTED) to improve sensing in cognitive radio networks. The novelty of the work lies in the exploitation of both the local binary/energy decisions and global binary decisions feedback from the fusion centre (FC). The proposed HDTED scheme is significant in providing better sensing performance compared to the conventional scheme with no hybrid combination of decisions. Furthermore, this paper develops an optimal secondary user selection algorithm for forwarding the local decisions to the FC, which helps reduce the number of forwarding bits for a lower-complexity signalling.
