This class will mainly follow the lecture notes of Prof. Ruediger Urbanke and Prof. Suhas Diggavi.
The review part will follow the lecture notes from the pre-requisite Principles of Digital Communications (PDC), taught in the summer semester by Prof. Bixio Rimoldi.

Attention!
The lecture notes bellow are just for reference. Sometimes we deviate from them and use other approaches in deriving and proving various concepts. Notations might differ as well. Printed notes might contain typos as well.
The main notes for this class are those given during the class time. (developed on the blackboard).
