Rate vs Fidelity for the Binary Source By S. P. LLOYD (Manuscript received May 5, 1976) Errors are deliberately introduced in the output of a binary message source to reduce the entropy rate.

We review various rate-adaptive modulation schemes for optical communications that enables maximizing the spectral efficiency at any channel condition, and analyze their theoretic benefits and weak

Abstract: A key problem in the control of packet-switched data networks is to schedule the data so that the queue sizes remain bounded over time.

In this paper we study energy-aware scheduling that trades energy consumption against a traditional performance measure of delay.

This paper addresses channel allocation for multi-user OFDM systems for real-time packet oriented data transmission.

Mathematical models of congestion control capture the congestion indication mechanism at the router in two different ways: Rate-based models, where the queue-length at the router does not explicitl

The rate-distortion dimension (RDD) of an analog stationary process is studied as a measure of complexity that captures the amount of information contained in the process.

Suppose in the communication system of Fig. 1, the source emits a sequence of continuous-valued random variables.

Optical networks are vulnerable to physical layer attacks; wiretappers can improperly receive messages intended for legitimate recipients.
