摘要
This research aims to compare and evaluate the performances of Polar code and LDPC code as the candidate of channel coding for 5G - mMTC scenario. Technical evaluation is done by assessing BLER, BER and coding gain for low block length with code rate = 1/2 using QPSK modulation over AWGN channel. Decoding schemes include Message Passing Algorithm (MPA) and Sum Product Algorithm (SPA) min-sum for LDPC code as well as Successive Cancelation (SC) and Successive Cancelation List (SCL) with L = 8 and L = 32 for Polar code. The result indicates that Polar code SCL decoder has the best performance with coding gain value 8.3 dB -10 dB. In addition, the Polar code SCL decoder also has a smaller Eb/N0 value with a difference of 1 dB - 3 dB compared to other coding schemes to obtain BLER 10(-4).
