Abstract
In spectrum sharing, Carrier Sense (CS) to detect other radio entities is very important in situations where coordination based on wired network is not easy for different operators or many deployments. Energy detection as a conventional CS is possible to detect unknown signals but so sensitive to noise variance that only a coarse spectrum sensing is performed in a short time. This paper proposes a novel CS for fine sensing based on LTE decoding in context of spectrum sharing in LTE systems among different operators by utilizing a prior knowledge of a control channel for resource scheduling. Numerical experiments show that the proposed method can achieve significant performances in terms of miss detection rate, false alarm rate, and the average of these.
