Communications Group
The Communications Group conducts research in a wide range of topics related to the physical and mathematical aspects of communication, often in collaboration with researchers in other disciplines such as signal processing, decision and control, circuits, computer engineering and neuroscience.
Applications include communication in wireless and wired networks, the Internet, biological systems, storage systems and data centers. Developing fundamental underlying principles and both identifying and meeting performance limits pervades this research.
Printer-friendly versionCommunication Systems: CSL researchers have devised sophisticated algorithms for wired and wireless multiaccess systems, which exploit spatial diversity and interference management. The implementation of these algorithms leads to efficient use of bandwidth, power and storage space, allowing for reliable, secure communication.
Bioinformatics: Researchers are demonstrating the utility of coding and information-theoretic ideas and methods for DNA sequence motif discovery; gene and metabolic-regulatory network studies; and genetic disease diagnostics. High-performance brain machine interfaces have been designed using statistical signal processing algorithms and feedback information theory.
Networks: Researchers have established distributed,low-complexity algorithms for routing and scheduling in communication networks, including peer-to-peer mechanisms. Strategies for distributed inference in wireless sensor networks have been developed. Methods for inference based on timing channels and traffic analysis, and related anonymity issues, are being explored.
