Abstract

In fifth generation wireless network, it becomes the critical challenge to offer high-bit rate data transmission and extensive networking services with low bit error rate (BER) performance. To achieve the requirements of 5G services, Orthogonal Frequency Division Multiplexing (OFDM) is a considerable technique for high quality communications. In addition, many channel coding schemes have been applied for mitigating performance degradation in terms of BER. Among them, LDPC and Turbo coding methods become the standard specification for high-bit rate data transmission in 5G network. There are so many difficulties and challenges how to apply this coding methods in OFDM with 5G standard specifications.In this paper, we conduct the analysis on two channel coding methods in multipath fading environment of 5G network: LDPC according to 5G specifications of Verizon 5G Technology Forum and Turbo codes by considering backward compatibility. According to our experimental results, we found that our coded OFDM in 5G network outperforms uncoded OFDM in 5G network. Moreover, Turbo coded OFDM with 5G specification achieve better performance with smaller BER than the LDPC coded Multipath OFDM in 5G network. That finding motivates to select Turbo codes as 5G channel coding resulting in cost savings because of backward compatibility to 3G and 4G.
