Analysis of Nonlinear Transition Shift and Write Precompensation in Perpendicular Recording Systems
Abstract—In high density perpendicular magnetic recording channels, nonlinear transition shift (NLTS) is one of the distortions that can degrade the system performance. Write pre...

Distortion Exponents for Multi-Relay Cooperative Networks with Limited Feedback
— In this paper, we consider the transmission of a Gaussian source in a multi-relay cooperative network, where limited channel state feedback is combined with separate source and...

Optimal Power Scheduling for Correlated Data Fusion in Wireless Sensor Networks via Constrained PSO
Optimal power scheduling for distributed detection in a Gaussian sensor network is addressed for both independent and correlated observations. We assume amplify-and-forward local p...
