General Heuristics for Nonconvex Quadratically Constrained Quadratic Programming
Jaehyun Park, Stephen Boyd
We introduce the Suggest-and-Improve framework for general nonconvex quadratically constrained quadratic programs (QCQPs). Using this framework, we generalize a number of known met…
Sparsity-Preserving Difference of Positive Semidefinite Matrix Representation of Indefinite Matrices
Jaehyun Park
We consider the problem of writing an arbitrary symmetric matrix as the difference of two positive semidefinite matrices. We start with simple ideas such as eigenvalue decompositio…
Concave Quadratic Cuts for Mixed-Integer Quadratic Problems
Jaehyun Park, Stephen Boyd
The technique of semidefinite programming (SDP) relaxation can be used to obtain a nontrivial bound on the optimal value of a nonconvex quadratically constrained quadratic program…
Simultaneous Wireless Information and Power Transfer in a Two-User OFDM Interference Channel
Zati Bayani Zawawi, Jaehyun Park, Bruno Clerckx
In this paper, we study the Simultaneous Wireless Information and Power Transfer (SWIPT) in a Single-Input Single-Output (SISO) two-user Orthogonal Frequency Division Multiplexing…
A Semidefinite Programming Method for Integer Convex Quadratic Minimization
Jaehyun Park, Stephen Boyd
We consider the NP-hard problem of minimizing a convex quadratic function over the integer lattice . We present a simple semidefinite programming (SDP) relaxation for ob…
MIMO Broadcasting for Simultaneous Wireless Information and Power Transfer: Weighted MMSE Approaches
Changick Song, Cong Ling, Jaehyun Park +1
We consider simultaneous wireless information and power transfer (SWIPT) in MIMO Broadcast networks where one energy harvesting (EH) user and one information decoding (ID) user sha…
Joint Wireless Information and Energy Transfer with Reduced Feedback in MIMO Interference Channels
Jaehyun Park, Bruno Clerckx
To determine the transmission strategy for joint wireless information and energy transfer (JWIET) in the MIMO interference channel (IFC), the information access point (IAP) and ene…
Multi-user Linear Precoding for Multi-polarized Massive MIMO System under Imperfect CSIT
Jaehyun Park, Bruno Clerckx
The space limitation and the channel acquisition prevent Massive MIMO from being easily deployed in a practical setup. Motivated by current deployments of LTE-Advanced, the use of…
Joint Wireless Information and Energy Transfer in a K-User MIMO Interference Channel
Jaehyun Park, Bruno Clerckx
Recently, joint wireless information and energy transfer (JWIET) methods have been proposed to relieve the battery limitation of wireless devices. However, the JWIET in a general K…
Joint Wireless Information and Energy Transfer in a Two-User MIMO Interference Channel
Jaehyun Park, Bruno Clerckx
This paper investigates joint wireless information and energy transfer in a two-user MIMO interference channel, in which each receiver either decodes the incoming information data…
