Performance Evaluation of Polar Coding Schemes for 5G Wireless Communication Networks

Abstract

Today's technology for 5G wireless connectivity is expanding quickly. Due to randomly occurring noise, interference, fading, device limitations, and other factors, the data delivered by the 5G wireless communication channel is vulnerable to error. Channel coding is an essential element for 5G wireless communication networks since it is used to address issues that arise during data transmission and reception in these networks. With outstanding error-correcting performance, polar coding is one of the best channel coding systems for 5G wireless communication networks. It can operate on binary memoryless symmetric channels. Successive cancellation (SC), successive cancellation list (SCL), and their modification are the most known polar decoding algorithms. In this work we have considered parameters such as bit error rate (BER) and frame error rate (FER) for different values of bit energy to noise spectral ratio (Eb/No), code rate, and list size to compare the performance of polar code with SC decoding, interleaving polar code with SC decoding (I-SC), cyclic redundancy check aided polar code with SCL decoding (CRC-A-SCL), interleaved cyclic redundancy check aided polar code with SCL decoding (I-CRC-A-SCL), cyclic redundancy check aided interleaved polar code with SCL decoding (CRC-A-I-SCL) and interleaved cyclic redundancy check aided interleaved polar code with SCL decoding (I-CRC-A-I-SCL) under BPSK modulation and AWGN channel model. We have also identified the most performance affecting parameters such as code rate, CRC length, and list size by comparing the BER and FER. From the result of our work, CRC-A-SCL polar coding scheme has a BER value of 0.94%, I-CRC-A-SCL polar coding scheme has 0.45%, CRC-A-I-SCL polar coding scheme has 0.14%, and I-CRC-A-I-SCL polar coding scheme has 0.03% at Eb/No of 2.4dB, list size 8 and CRC length 16 over AWGN channel and BPSK modulation. From this result, I-CRC A-I-SCL polar coding scheme has better performance and it is the best polar coding scheme for 5G wireless communication networks.
