Temporally coherent luminance-to-luma mapping for high dynamic range video coding with H.264/AVC
This paper presents a technique for the efficient compression of high dynamic range video (HDR) sequences. Such video sequences usually represent several orders of magnitude of r...

Interference alignment in single-beam MIMO networks via homotopy continuation
In this paper we consider the application of a homotopy-continuation based method for finding interference alignment (IA) solutions for the deterministic K-user multiple-input mu...

Rate control for PSD limited multiple access systems through linear programming
In this paper we discuss rate control for multiuser multicarrier systems, where the transmitter has a single antenna and is subject to a PSD mask limitation while the receiver has...

Joint source-channel rate control for pixel-domain distributed video coding
We study the scenario of pixel-domain distributed video coding for noisy transmission environments and propose a method to allocate the available rate between source coding and ch...
