Modulation Codes for Flash Memory Based on Load-Balancing Theory
Fan Zhang, Henry D. Pfister
In this paper, we consider modulation codes for practical multilevel flash memory storage systems with cell levels. Instead of maximizing the lifetime of the device [Ajiang-isit07-…
Can Iterative Decoding for Erasure Correlated Sources be Universal?
Arvind Yedla, Henry D. Pfister, Krishna R. Narayanan
In this paper, we consider a few iterative decoding schemes for the joint source-channel coding of correlated sources. Specifically, we consider the joint source-channel coding of…
A Rate-Distortion Perspective on Multiple Decoding Attempts for Reed-Solomon Codes
Phong S. Nguyen, Henry D. Pfister, Krishna R. Narayanan
Recently, a number of authors have proposed decoding schemes for Reed-Solomon (RS) codes based on multiple trials of a simple RS decoding algorithm. In this paper, we present a rat…
Power Allocation Strategies and Lattice Based Coding schemes for Bi-directional relaying
Makesh Pravin Wilson, Krishna Narayanan
We consider a communication system where two transmitters wish to exchange information through a half-duplex relay in the middle. The channels between the transmitters and the rela…
Transmitting an analog Gaussian source over a Gaussian wiretap channel under SNR mismatch
Makesh Pravin Wilson, Krishna Narayanan
In this work we study encoding/decoding schemes for the transmission of a discrete time analog Gaussian source over a Gaussian wiretap channel. The intended receiver is assumed to…
A Combinatorial Study of Linear Deterministic Relay Networks
S. M. Sadegh Tabatabaei Yazdi, Serap A. Savari
In the last few years the so--called "linear deterministic" model of relay channels has gained popularity as a means of studying the flow of information over wireless communication…
