Joint Linear Processing for an Amplify-and-Forward MIMO Relay Channel with Imperfect Channel State Information

EURASIP Journal on Advances in Signal Processing, 2010
The problem of jointly optimizing the source precoder, relay transceiver, and destination equalizer has been considered in this paper for a multiple-input-multiple-output (MIMO) amplify-and-forward (AF) relay channel, where the channel estimates of all ...

A class of nonconvex semidefinite programming in which every KKT point is globally optimal

We consider a special class of nonconvex semidefinite programming problems and show that every point satisfying the Karush--Kuhn--Tucker (KKT) conditions is globally optimal despite nonconvexity. This property is related to pseudoconvex optimization. This class of problems is motivated by an eigenfrequency topology optimization problem in structural ...

Impact of endogenous learning curves on maritime transition pathways

Environmental Research Letters
The maritime industry is a crucial hard-to-abate sector that is expected to depend on high-energy density renewable liquid fuels in the future. Traditionally, decarbonization pathways have been assessed assuming exogenous cost trajectories for renewable ...

DC programming and DCA for nonconvex optimization/ global optimization in mixed integer programming : Codes and applications

, 2013
Based on theoretical and algorithmic tools of DC programming and DCA, the research in this thesis focus on the local and global approaches for non convex optimization and global mixed integer optimization. The thesis consists of 5 chapters. The first chapter presents fundamentals of DC programming and DCA, and techniques of Branch and Bound method (B&B)
