For 5G enhanced mobile broad band (eMBB) services, 3GPP has selected Quasi Cyclic LDPC (QC-LDPC) and Polar codes for data and control channel coding respectively. The data channel requirements in respect to message block lengths and channel code rates are different from the control channel requirements. The error correction performance degrades with decreased message lengths. Further, So far designed polar codes are SNR dependent. Hence, this paper considers polar codes designed based on method independent of SNR and performance evaluation of the QPSK modulated QC-LDPC codes and polar codes for 5G eMBB service over AWGN is carried out using block error rate (BLER) as the performance measures.
