چکیده

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.

Quantized Oversampled Filter Banks with Erasures

Oversampled filter banks can be used to enhance resilience to erasures in communication systems in much the same way that finite-dimensional frames have previously been applied. This paper extends previous finite dimensional treatments to frames and signals in l2(Z) with frame expansions that can be implemented efficiently with filter banks. It is shown that tight frames attain best performance...

Joint Source-Channel Coding Based on Cosine-Modulated Filter Banks for Erasure-Resilient Signal Transmission

This paper examines erasure resilience of oversampled filter bank (OFB) codes, focusing on two families of codes based on cosinemodulated filter banks (CMFB). We first revisit OFBs in light of filter bank and frame theory. The analogy with channel codes is then shown. In particular, for paraunitary filter banks, we show that the signal reconstructionmethods derived from the filter bank theory a...

A New Class of Seeded Real Lapped Tight Frame Transforms

We propose a design procedure for the real, equal-norm, lapped tight frame transforms (LTFTs). These transforms have been recently proposed as both a redundant counterpart to lapped orthogonal transforms and an infinite-dimensional counterpart to harmonic tight frames. In addition, LTFTs can be efficiently implemented with filter banks. The procedure consists of two steps. First, we construct n...
