Course description:

Electrical and computer engineers have played a central role in the design of modern information and communication systems. These highly successful systems work reliably and predictably in highly variable and chaotic environments. Probability models are one of the tools that enable the designer to make sense out of the chaos and to successfully build systems that are efficient, reliable, and cost effective. This course describes the theory underlying probability models as well as the basic techniques used in the development of such models.

Venue: Monday-Wednesday 2:55--4:10, Room PHL 407

Webpage: http://blackboard.cornell.edu

Format: Seminar. no exam. projects and presentations

Course Material: Research papers and book chapters

Information Theory (those interested are encouraged to take ECE 5620 simultaneously)

Instructor: Prof. Salman Avestimehr. 325 Rhodes Hall. x5-9915, avestimehr [at] ece

Course description:

Claude Shannon characterized the fundamental limit of reliable communication over a point-to-point communication channel. Until recently, there has been only limited success in extending the theory to a network of interacting nodes. Progress has been made in the past decade, driven both by engineering interest in wireless networks as well as conceptual advances such as network coding. This seminar indents to cover these advances and provide a fresh perspective on the state-of-the-art of the field. Specific topics include recent generalizations of the Ford-Fulkerson Theorem, applications of “Matroid Theory” and “Linking Systems” in network information flow,  cooperation techniques in wireless relay networks, and interference management strategies in wireless networks.

Tentative Topics:

Single-source single-destination wireline networks. Ford-Fulkerson Theorem.

Multicast in wireline networks. Advantage of network coding over routing.

Linear network coding. Multicast capacity of wireline networks.

Algorithms for directed acyclic graphs. Algorithms for cyclic graphs.

Beyond multicast. Insufficiency of linear codes.

Two-unicast problem.

Wireless networks. Deterministic modeling of wireless channels.

Single-source single-destination deterministic wireless networks (i.e. wireless relay networks).

Capacity of deterministic relay networks. Generalization of Ford-Fulkerson Theorem.

Connections to Matroid Theory and Linking Systems.

Connections between the deterministic model for wireless channels and the Gaussian model.

Approximate capacity of Gaussian relay networks.

Beyond single--source single--destination wireless networks. Interference channel.

Capacity of the interference channel.

Webpage: http://blackboard.cornell.edu

Format: Seminar. no exam. projects and presentations

Course Material: Research papers and book chapters

Pre-requisites: Probability and random processes (ECE 4110 or equivalent),

Prof. Lang Tong. 384 Rhodes Hall. x5-3900, ltong [at] ece

Course description:

The probabilistic method is a powerful tool in tackling many problems in discrete mathematics. Roughly speaking, the method works as follows: Trying to prove that a structure with desired property exists, one defines an appropriate probability space of structures and then shows that the desired properties hold in this space with positive probability. In this seminar series we aim to learn this powerful tool and investigate its application in communication theory problems.

Tentative Topics:

Illustration of the probabilistic method:

Basic examples

Distributing keys in multi-user crypto-systems

Local Lemma and simple applications of it

Linearity of Expectation and its Applications

Codes, Games and Entropy

Lovasz Local Lemma and its applications to routing and tracking

Correlation Inequalities

Martingales
