Downlink and Uplink Cooperative Transmission for Primary Secrecy Based Cognitive Radio Sensor Networks by Dawei Wang, Pinyi Ren, Qinghe Du, Li Sun, Yichen Wang

“…Aiming at allocating more licensed spectrum to wireless sensor nodes (SNs) under the constraint of the information security requirement of the primary system, in this paper, we propose a cooperative relaying and jamming secure transmission (CRJS) scheme in which SNs will relay primary message and jam primary eavesdrop concurrently with SN's downlink and uplink information transmission in cognitive radio sensor networks (CRSNs). In our proposed CRJS scheme, SNs take advantages of physical layer secure technologies to protect the primary transmission and acquire some interference-free licensed spectrum as a reward. …”

Analysis of propagation and coverage performance of indoor single-carrier radio signals in the terahertz bands by Mugen PENG, Chuang YANG, Tianhang ZHOU

“…To tackle the problem that radio signal in the terahertz band had different features compared to that in the conventional spectrum, which restricted its application to indoor communication scenarios, a modified propagation model of terahertz radio signal was proposed.Based on the model, the propagation and coverage performances of wide-band single-carrier terahertz radio signal were analyzed.In particular, the wide-band terahertz channel transfer function was constructed, taking the absorption loss introduced by the thickness of the obstacles into account.Using the ray tracing technique, the impacts of the obstacles’ thickness and the bandwidth on the propagation and coverage performances were examined, showing that the coverage performance can be improved by leveraging the reflections from the non-line-of-sight obstacles.Moreover, the trade-off between the coverage radius and the capacity of terahertz communications is revealed, and it is further found that the theoretical spectral efficiency decreases as the carrier frequency of terahertz radio signal increases.…”
