As a result of recent developments in coding theory, the Third Generation Partnership Project (3GPP) has decided to incorporate polar codes and LDPC codes into 5G reforming the entire channel coding paradigm in cellular networks. In the first part of this talk, we provide a brief overview of the most recent advances in channel coding standardization in 5G wireless networks. Also, motivated by various new features in 5G we describe two emerging scenarios for channel coding, namely, non-stationary scenarios and low capacity channels. In the second part, we discuss constructing polar codes for non-stationary channels. In the third part of the talk, we discuss channel coding, and in particular polar codes, in low-capacity scenarios that are becoming increasingly important for the integration of IoT into the 5G cellular network.

Hessam Mahdavifar is an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan. He received the B.Sc. degree from Sharif University of Technology, Tehran, Iran, in 2007, the M.Sc. and Ph.D. degrees from the University of California San Diego (UCSD), USA, in 2009, and 2012, respectively, all in Electrical Engineering. He was with the Samsung Mobile Solutions Lab between 2012 and 2016. His general research interests are in coding theory, wireless communications, and security. He has won several awards including the Best Paper Award in the 2015 IEEE International Conference on RFID, the UCSD Shannon Memorial Fellowship, and two Silver Medals at the International Mathematical Olympiad.
