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...
We consider the problem of sensor localization in a wireless network in a multipath environment, where time and angle of arrival information are available at each sensor. We propose a distributed algorithm based on belief propagation, which allows sensors to cooperatively self-localize with respect to one single anchor in a multihop network. Simulations show that although the network is loopy, the...
Coordinated multi-point transmission/reception (CoMP), in which base stations (BSs) cooperate during the downlink, has been identified as a tool for improving user rates and mitigating interference. The cost for existing coordination schemes with joint processing is the heavy exchange of channel state information and signal information over backhaul links. In this paper, we propose a decentralized...
