Comparative Performance Analysis of Polar Coding Schemes for 5G and Beyond Enhanced Mobile Broadband Communication

Abstract

Sinceewe are inethe era of everefast growingecommunication technology, there are so many areas that are struggling to improve the quality of service in the customer satisfaction at anywhere and anytime. The emergingeof the 5G and beyond enhanced communication system is focused on improving the quality of services in the way of communication, reliability of data transmission, and the security of the systems. The need for ultra-reliable error freeecommunications is emerging in many application area like mobile broadband communication, where good connectivity is essential to the transmission of reliable information in real scenario. Channel coding techniques such as convolutional and Turbo codes that were used in 4G LTE are replaced by polar codes and LDPC codes for 5G and beyond system. Since PC are recent than low density parity check codes and for polar coding schemes different improvements can be made under different parameters variation to increase the performance. In this thesis the performance metric parameters such as bit error rate, block error rate and computational complexity for different value of bit energy to noise spectral ratio, block length, code rate and list size for polar code with successive cancellation decoding, interleaving polar code with successive cancellation decoding, cyclic redundancy check aided polar code with successive cancellation list decoding and cyclic redundancy check aided interleaving polar code with successive cancellation list decoding are analyzed for noisy binary erasure channels. And also the most performance affecting parameters such as code rate, CRC size, and list size by comparing the BER, BLER and computational complexity are identified. For theesimulation purpose Matlab R2020a is used. For better comparisonoof the polar coding schemes speech signal and text is used in the encoding and decoding process. Finally, the results areiinterpreted, discussions are made and conclusion anddfuture work is drawn based on the results obtained. Based on the results obtained CRC aided interleaving polar code with SCLD has BER of 0.02% and CRC aided polar with SCLD has 0.19% at Eb/No of 2.2dB, list size 8 and CRC size 16 over BPSK AWGN channel for a code rate of 1/2. The uncoded case has BER of 3.75% at the same Eb/No and PC without CRC and interleaving has BER of 3.09%.
