Improved Energy Detector with Weights for Primary User Status Changes in Cognitive Radio Networks
This paper presents an improved energy detector (ED) with weights to improve detection performance in this situation that the primary user's status changes as arriving or leaving randomly in cognitive radio networks. The idea is derived from the concept of unequal scale sampling such that the i...
