LogGOPSim: simulating large-scale applications in the LogGOPS model
We introduce LogGOPSim--a fast simulation framework for parallel algorithms at large-scale. LogGOPSim utilizes a slightly extended version of the well-known LogGPS model in combin...

On the Rate Duality of MIMO Interference Channel and Its Application to Sum Rate Maximization
In this paper, we establish a rate duality between the forward and reverse links of MIMO interference channel, where the reverse links are obtained by exchanging the roles of trans...

Low-Complexity SQR-Based Decoding Algorithm for Quasi-Orthogonal Space-Time Block Codes
— In this paper, we propose a new decoding algorithm for quasi-orthogonal space-time block codes (QOSTBCs) which achieves near Maximum Likelihood (ML) performance while substanti...

Constrained Decompositions of Integer Matrices and their Applications to Intensity Modulated Radiation Therapy
We consider combinatorial optimization problems arising in radiation therapy. Given a matrix I with non-negative integer entries, we seek for a decomposition of I as a weighted su...
