Robust Cyclic Space-Frequency Filtering for BICM-OFDM with Outdated CSIT
— In this paper, we introduce robust cyclic space– frequency (CSF) filtering for systems combining bit–interleaved coded modulation (BICM) and orthogonal frequency division ...

Approximation algorithms for channel allocation problems in broadcast networks
We study two packing problems that arise in the area of dissemination-based information systems; a second theme is the study of distributed approximation algorithms. The problems c...
