ELE 531 - Multi-user Communication Theory

Professor Sergio Verdú

Modeling and analysis of data communication systems with more than one source and/or destination, e.g., computer networks, satellite broadcast channels and packet-radio networks. Topics include queueing theory and networks of queues; network routing and flow control; multi-user information theory; multi-user detection in multiple-access channels; and multiple-access packet-broadcasting protocols.
