Public-Key Locally-Decodable Codes
In this paper we introduce the notion of a Public-Key Encryption Scheme that is also a Locally-Decodable Error-Correcting Code (PKLDC). In particular, we allow any polynomialtime ...

Dirty Paper Coding using Sign-bit Shaping and LDPC Codes
Dirty paper coding (DPC) refers to methods for pre-subtraction of known interference at the transmitter of a multiuser communication system. There are numerous applications for DPC...

On Generating Soft Outputs for Lattice-Reduction-Aided MIMO Detection
— Lattice Reduction (LR) aided MIMO detection has been shown to provide near-optimal hard outputs. However soft outputs are required in practical systems to fully exploit gains f...

Unified decoder architecture for LDPC/turbo codes
Low-density parity-check (LDPC) codes on par with convolutional turbo codes (CTC) are two of the most powerful error correction codes known to perform very close to the Shannon li...

A Tight Bound on the Performance of a Minimal-Delay Joint Source-Channel Coding Scheme
An analog source is to be transmitted across a Gaussian channel in more than one channel use per source symbol. This paper derives a lower bound on the asymptotic mean squared erro...
