Filter bank frame expansions with erasures

Abstract--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 2( ) and focus on a filter-bank implementation of the system. We present results in parallel, or versus 2( ), and show that uniform tight frames, as well as newly introduced strongly uniform tight frames, provide the best performance.
