In this paper, we consider secure transmission for the full duplex relay network. Aiming to improve the physical layer security, we propose a full duplex hybrid relaying-and-jamming (FDHRJ) scheme. In the FDHRJ scheme, we design a pre-coding matrix to form a jamming signal and let the relay simultaneously transmit both the desired signal and the jamming signal every slot. The destination can decode...
In this paper, a mmWave unified access and back-haul (UAB) network is presented, where both radio access (RA) and backhaul (BH) share the same millimeter wave bands. Considering uniform resource allocation of RA and BH radio resource for all pico stations, which can well mitigate the interference among pico stations, the capacity of UAB is mainly influenced by the allocated resource ratio between...
For industrial applications, real-time performance is a critical issue of wireless sensor network. IEEE802.15.4 protocol has greater potential compared with other protocols. However, it can??t meet the strict requirements of real-time performance in industrial environment. After analyzing the demands of versatile applications in industrial environment and guaranteed time slots (GTS) mechanism in the...
