Professor Prakash Narayan's research is in the field of multiuser information theory and coding. It deals with the study of probabilistic models for compression of multiple signals, reliable transmission among several users and secure communication. The main objectives are characterizations of the fundamental limits of performance, and analysis of coding, modulation and signal processing techniques for attaining this performance. Applications lie in a variety of communication networks.
Narayan's current research focuses on understanding how in specific multiterminal systems, correlation among the signals at the terminals can be exploited, through managed cooperation, in designing efficient methods for signal sampling, compression, transmission and assuring information security. Provable limits of performance and techniques for achieving them are analyzed.
Specific research projects include studies of: connections between common randomness generation by multiple terminals, network secret key generation, and combinatorial tree packing in multigraphs; secure function computation; reliable communication over hybrid radio frequency and free space optical communication systems; and sampling-quantization-distortion tradeoffs in thermal profile estimation for multicore processor chips.
