摘要

在频谱共享中,载波感知(Carrier Sense, CS)检测其他无线电实体在基于有线网络的不同运营商或多个部署难以协调的情况下是非常重要的。能量检测作为传统的CS可以检测到未知信号,但由于对噪声方差非常敏感,因此只能在短时间内进行粗谱检测。本文利用控制信道的先验知识进行资源调度,提出了一种基于LTE解码的基于不同运营商之间LTE系统频谱共享的新型精细传感CS。数值实验表明,该方法在脱靶率、虚警率及平均值方面均取得了较好的效果。

Carrier sense towards spectrum sharing via control channel in LTE systems
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.
