Ordered Metrics and Their Applications

Description 

Professor Alexander Barg (ECE/ISR) is the principal investigator for Ordered Metrics and Their Applications. The three-year, $472K grant will fund research into the properties and applications of polar codes for communication systems. Polar codes are a new method of coding information for transmission over noisy channels that for the first time realizes the full potential of Shannon’s theorems related to data rate and transmission reliability. Polar codes have been shown to advance a range of classical and new information-theoretic problems that rely on efficient encoding of the data. Barg’s project addresses the properties of polar codes in nonbinary communication channels, the design of optimal polarizing transformations, and applications to unequal error protection, hierarchical source coding, broadcast channels, signal design, and other problems of importance for network communication.
