About the lecture
What if information could be transmitted through a noisy channel using almost no power? Or messages could reach their intended devices without conventional addressing information?
Information theory helps us understand the fundamental limits of how information is compressed, represented and transmitted. Yet, in some scenarios, these limits lead to unexpected possibilities.
In this lecture, Professor Wei Yu explores two surprising findings: the possibility of transmitting information at a positive rate using infinitesimal transmit power, and communicating with selected active devices in large wireless networks without the usual addressing overhead.
Discover how these findings challenge conventional expectations and what they could mean for cooperative communications and massive random access in wireless networking.
