Approximately achieving Gaussian relay network capacity with lattice codes
Abstract--Recently, it has been shown that a quantize-mapand-forward scheme approximately achieves (within a constant number of bits) the Gaussian relay network capacity for arbitr...

Scalable predictive coding by nested quantization with layered side information
An efficient scalable predictive coding method is proposed for the Wyner-Ziv problem, using nested lattice quantization followed by multi-layer Slepian-Wolf coders (SWC) with laye...

Worst-Case to Average-Case Reductions Based on Gaussian Measures
We show that finding small solutions to random modular linear equations is at least as hard as approximating several lattice problems in the worst case within a factor almost line...
