Collaborative spectrum sensing from sparse observations using matrix completion for cognitive radio networks
— In cognitive radio, spectrum sensing is a key component to detect spectrum holes (i.e., channels not used by any primary users). Collaborative spectrum sensing among the cognit...

Jitter-Induced Power/ground Noise in CMOS PLLs: A Design Perspective
CMOS Phase-locked loops (PLL) are ubiquitous in RF and mixed-signal integrated circuits. PLLs are very sensitive to noise fluctuations on the power and ground rails. In this paper...
