Title: Channel Coding in 5G: What is New?
Abstract: 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. Polar codes are the first class of codes that provably achieve the fundamental limit of capacity for a wide range of channels with explicit constructions and low encoding and decoding complexity. In the first part of this talk, we provide a brief overview of polar codes and describe the most recent advances towards incorporating them in 5G wireless networks. In the second part, we discuss the finite-length scaling behavior of polar codes and how to characterize them in non-stationary and time-varying 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.
