Emerging Coding Techniques

Major telecommunications companies are on the run for the standardization of the codes and protocols for the new 5G technology, to be released in 2020. Following this trend, the reading group of this semester will mostly focus on new mathematical tools (or old ones, revisited in a new context) for coding. The preference is for constructive coding techniques, which may a technological impact in the near future. Each exposition is intended to explain, in sufficient detail, the main idea of one major emerging coding technique. As usual, blackboard talks are most appreciated.

This is an informal reading group, where each volunteer presents a topic based on a recent paper or a book chapter.
The reading group will take place in Room 503, usually on Mondays 14:00-15:30 . If you want to give a talk or propose a new topic, drop me an e mail (
