Lower Bounds on the Rate-Distortion Function of LDGM Codes
A. G. Dimakis, M. J. Wainwright, K. Ramchandran
A recent line of work has focused on the use of low-density generator matrix (LDGM) codes for lossy source coding. In this paper, wedevelop a generic technique for deriving lower b…
Bits through ARQs
Krishnan Eswaran, Michael Gastpar, Kannan Ramchandran
A fundamental problem in dynamic frequency reuse is that the cognitive radio is ignorant of the amount of interference it inflicts on the primary license holder. A model for such a…
Network Coding for Distributed Storage Systems
Alexandros G. Dimakis, P. Brighten Godfrey, Martin J. Wainwright +1
Peer-to-peer distributed storage systems provide reliable access to data through redundancy spread over nodes across the Internet. A key goal is to minimize the amount of bandwidth…
