Joint rate-and-power allocation for multi-channel spectrum sharing networks
abstract, we propose a study on joint rate-and-power allocation problem for multi-channel spectrum sharing networks (SSNs). We formulate this cross-layer optimization problem as a...

Analysis of Handoff Interference and Outage along Arbitrary Trajectories in Cellular Networks
We introduce a new system performance measure due to handoff called handoff interference, which characterizes the additional interference noise induced by the handoff process. The ...

Constraint-aware robustness insertion for optimal noise-tolerance enhancement in VLSI circuits
Reliability of nanometer circuits is becoming a major concern in today’s VLSI chip design due to interferences from multiple noise sources as well as radiation-induced soft erro...
