Successive Refinement for Hypothesis Testing and Lossless One-Helper Problem
Abstract--We investigate two closely related successive refinement (SR) coding problems: 1) In the hypothesis testing (HT) problem, bivariate hypothesis H0 : PXY against H1 : PXPY ...

Worst case burstiness increase due to FIFO multiplexing
We consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem a...
