Polar Code: The Channel Code contender for 5G scenarios

Channel Coding for the 5G wireless networks is facing novel challenges to endorse innumerable emerging use cases and applications with miscellaneous performance aspects. With respect to existing state of art codes; 5G channel Codes have diverse requirements of code lengths and rates, as well as throughput, latency and decoding complexity. Therefore, Turbo codes and LDPC codes that played key enablers in 3G and 4G systems are already unproven for many new 5G applications. Polar code is believed as prominent breakthrough in channel coding theory. It guarantees apical performance for 5G scenarios and hence it is considered as a promising candidate for the 5G New Radio. This paper accentuates on the suitability of polar codes for the 5G scenarios. Polar code appropriateness for URLLC and mMTC scenarios is shown in simulation results.
