Communication Theory Research Group
The field of communication theory is devoted to the design of
digital communications systems. At its core is the mathematics
that underlies the traditional physical-layer functions of modulation,
coding, equalization and synchronization. As such, it involves
a mix of information theory, digital signal processing, and
applied mathematics. In recent years, the scope of communication
theory has broadened to encompass multiple users as well; thus
modern communication theory provides a physical-layer view
of many seemingly network-related concepts such as interference,
multiple-access, contention, relaying, and cooperation.
Although a relatively young field, its impact is already widespread;
advances in communication theory have made possible deep-space telemetry,
high-speed wireless local-area networks, and cellular telephony.
The Communication Theory Research Group is working on a variety
of exciting projects in this important area.
