The Posterior Matching Feedback Scheme for Joint Source-Channel Coding with Bandwidth Expansion
When transmitting a Gaussian source over an AWGN channel with an input power constraint and a quadratic distortion measure, it is well known that optimal performance can be obtain...

Unbalanced Expanders and Randomness Extractors from Parvaresh-Vardy Codes
We give an improved explicit construction of highly unbalanced bipartite expander graphs with expansion arbitrarily close to the degree (which is polylogarithmic in the number of ...

Storage coding for wear leveling in flash memories
NAND flash memories are currently the most widely used type of flash memories. In a NAND flash memory, although a cell block consists of many pages, to rewrite one page, the whole ...

A spectral approach to recursive end-to-end distortion estimation for sub-pixel motion-compensated video coding
Error resilient video coding critically relies on the accuracy of endto-end distortion estimation. An established solution, the recursive optimal per-pixel estimate (ROPE), is bas...
