In practical implementations of single-antenna full-duplex (FD) radios, the imperfect isolation between the transmit (TX) and receive (RX) ports of the circulator causes the leakage of a strong self-interference (SI) component. This issue reduces both the spectral and energy efficiency of the device. State-of-the-art SI cancellation (SIC) solutions mitigate this problem, however they also constrain...

Performance of in-band full-duplex (FD) radios is typically hindered by practical hardware limitations of the circulator, whose signal leakage may cause the presence of very large self-interference (SI) in the receiver (RX) chain. This causes both spectral and energy efficiency reduction for the FD radio. In this work, a novel energy-recycling single-antenna FD architecture, in which an energy harvester...
In this paper, a novel transformer-less interleaved four-phase high step-down conversion ratio dc-dc converter with low switch voltage stress is proposed. In the proposed converter, the new capacitors switching circuits are combined with interleaved four-phase buck converter in order to get a high step-down conversion ratio without adopting an extreme short duty ratio. Based on the capacitive voltage...
We propose a phased waking three dimensional coverage scheme based on hibernation of redundant nodes for the limited energy of nodes and redundancy in wireless sensor networks. A large number of sensor nodes are randomly deployed in the monitoring region and the redundant nodes can hibernate which will be waken by phases after the on-duty nodes are exhausted. Each node??s state can be determined at...
