Code restructuring for improving cache performance of MPSoCs
— One of the critical goals in code optimization for MPSoC architectures is to minimize the number of off-chip memory accesses. This is because such accesses can be extremely cos...

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 ...

Hyperspectral Image Compression: Adapting SPIHT and EZW to Anisotropic 3-D Wavelet Coding
Abstract--Hyperspectral images present some specific characteristics that should be used by an efficient compression system. In compression, wavelets have shown a good adaptability...
