Full duplex systems are more spectrally efficient than conventional half duplex systems if the self-interference (SI) can be significantly mitigated. Digital cancellation is one of the lowest complexity SI cancellation techniques in full duplex systems. However, its mitigation capability is mainly limited by the power amplifier (PA) nonlinear distortion. In this paper, to cancel the SI induced by...
In order to build open-loop large scale RFID applications, it is necessary to establish public RFID service infrastructure, the key issue is to build efficient and robust RFID code resolution network. But there exist some problems, such as load balancing, single node failure, etc. On the basis of recent research, according to features of governmental administration and enterprise applications, a hierarchical...
In order to build large-scale RFID applications, it is necessary to establish public RFID service infrastructure, the essential task is to build efficient and secure RFID code resolution network. Aiming at alleviating the problems in load balancing, single node failure tolerance and security of resolution network, based on related standards and research works, a hierarchical P2P based RFID code resolution...
