Digital Communications Lecture Notes Fall 2009



Class Organization

Textbook Few textbooks cover solely digital communications (without analog) in an introductory communi-
cations course. But graduates today will almost always encounter / be developing solely digital communication
systems. So half of most textbooks are useless; and that the other half is sparse and needs supplemental material.
For example, the past text was the standard text in the area for an undergraduate course, Pr ....etc

TCP-Aware Channel Allocation in CDMA Networks-IEE Jan. 2009

Abstract

explores the use of rate adaptation in cellular networks to maximize throughput long-lived TCP sessions. We focus on the problem of maximizing the throughput of TCP connections and propose a joint optimization of MAC and physical layer parameters with respect to TCP sending rate. In particular, propose a simple TCP-aware channel scheduler that adapts the wireless channel rate to changes in the TCP sending rate and explore its performance for both single and multiple con ....etc

The Great Recession of 2008-2009



Introduction
The global financial crisis of 2007 has cast its long shadow on the economic fortunes of many
countries, resulting in what has often been called the Great Recession .1 What started as
seemingly isolated turbulence in the sub-prime segment of the US housing market mutated
into a full blown recession by the end of 2007. The old proverbial truth that the rest of the
world sneezes when the US catches a cold appeared to be vindicated as system ....etc

Multiple Routing Configurations for Fast IP Network Recovery (IEE-2009)

Abstract:

As the Internet takes an increasingly central role in our communications infrastructure,
the slow convergence of routing protocols after a network failure becomes a growing problem.
To assure fast recovery from link and node failures in IP networks, we present a new recovery
scheme called Multiple Routing Configurations (MRC). Our proposed scheme guarantees
recovery in all single failure scenarios, using a single ....etc
