Systems Seminar
Exploiting Feedback for Low-Delay Ultra-High-Reliability Communication
Prof. Stark Draper
ECE Dept.
UW-Madison
Abstract
In this talk I'll discuss a theme of work that seeks to develop
fundamental architectural insight into how the availability of
feedback should impact the design of physical-layer communication
systems. I describe how the availability of feedback radically shifts
the achievable tradeoff between reliability and latency in digital
communications. We'll see how this tradeoff is further modified by
the particular data consumption characteristics of one's application
(say, block-based-FTP versus streaming data). By bringing such
architectural insight to bear on network protocol and error-correction
code design we hope to boost massively the performance of myriad
applications that have either very tight delay or reliability
tolerances, such as streaming video or control over networks.
Keywords: block coding, erasure decoding, noisy feedback, streaming transmission
Time and Place: Wed., Apr. 30, at 3:30 pm in 4610.
