Multilevel Coding Schemes for Compute-and-Forward
Brett Hern, Krishna Narayanan
We investigate techniques for designing modulation/coding schemes for the wireless two-way relaying channel. The relay is assumed to have perfect channel state information, but the…
Joint Source-Channel Coding with Correlated Interference
Yu-Chih Huang, Krishna R. Narayanan
We study the joint source-channel coding problem of transmitting a discrete-time analog source over an additive white Gaussian noise (AWGN) channel with interference known at trans…
LDPC Code Design for Transmission of Correlated Sources Across Noisy Channels Without CSIT
Arvind Yedla, Henry D. Pfister, Krishna R. Narayanan
We consider the problem of transmitting correlated data after independent encoding to a central receiver through orthogonal channels. We assume that the channel state information i…
On the Queueing Behavior of Random Codes over a Gilbert-Elliot Erasure Channel
Parimal Parag, Jean-Francois Chamberland, Henry D. Pfister +1
This paper considers the queueing performance of a system that transmits coded data over a time-varying erasure channel. In our model, the queue length and channel state together f…
On Multiple Decoding Attempts for Reed-Solomon Codes: A Rate-Distortion Approach
Phong S. Nguyen, Henry D. Pfister, Krishna R. Narayanan
One popular approach to soft-decision decoding of Reed-Solomon (RS) codes is based on using multiple trials of a simple RS decoding algorithm in combination with erasing or flippin…
A Rate-Distortion Exponent Approach to Multiple Decoding Attempts for Reed-Solomon Codes
Phong S. Nguyen, Henry D. Pfister, Krishna R. Narayanan
Algorithms based on multiple decoding attempts of Reed-Solomon (RS) codes have recently attracted new attention. Choosing decoding candidates based on rate-distortion (R-D) theory,…
