Filter bank frame expansions with erasures

We study frames for robust transmission over the Internet. In our previous work, we used quantized finite-dimensional frames to achieve resilience to packet losses; here, we allow the input to be a sequence in l/sub 2/(Z) and focus on a filter-bank implementation of the system. We present results in...

Zusammenfassung:We study frames for robust transmission over the Internet. In our previous work, we used quantized finite-dimensional frames to achieve resilience to packet losses; here, we allow the input to be a sequence in l/sub 2/(Z) and focus on a filter-bank implementation of the system. We present results in parallel, R/sup N/ or C/sup N/ versus l/sub 2/(Z), and show that uniform tight frames, as well as newly introduced strongly uniform tight frames, provide the best performance.
