Polar Codes Analysis of 5G Systems

In this paper, we investigate the achievements and challenges of using polar codes in 5th generation New Radio (5G-NR) communications systems. Polar codes are considered the promising technique to solve the problems that emerged in previous generation wireless communications systems such as latency, complexity, error correction capability, network infrastructure and Quality of Service (QoS). Polar codes have been chosen as the standard control channels in 5G-NR by the 3rd Generation Partnership Project (3GPP). In this work, we compare polar codes with the two competitor codes that might be used in 5G-NR, which are turbo codes and Low Density Parity Check (LDPC) Codes. The comparison between them focused on advantages and disadvantages of each code scheme to make it easy understanding the performance, achievements, and challenges of each code.
