A New Primary User Sensing Approach Based on LTE Wireless Sensor Networks
Guan Nan Li, Yang Li, Ning Zhang, Kai Cui · 2009
Long term evolution (LTE) is one of the most effective techniques to improve the capacity and bit of communication. In order to detect the presence of the primary user signal with high probability in LTE, spectrum sensing is a fundamental requirement to achieve the goal of cognitive radio (CR). we consider cooperative spectrum sensing in LTE based on energy detection. This is a basic condition for CR utilizating the "spectrum hole". In this paper, detection performance of the frequency spectrum on CR receiver is investigated. The experiment shows that our new approach can heighten the spectrum utilization of CR users in LTE.
