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 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.
