Channel Coding Analysis for NB-IoT Up-Link Transport Channel

Error detection and error correction are one of the pillars of any communication system which serve as an error correction mechanism and improve signal quality. In this paper, we present a turbo channel coding algorithm for up-link transport channel in narrowband internet of things. The proposed channel coding uses 24-bit CRC syndrome calculator and turbo codes with a tail bit convolutional encoder to transmits NB-IoT packet date from MAC layer to physical layer over AWGN. In addition, we carried out performance analysis and simulation of the proposed algorithm in accordance with NB-IoT requirement specified by 3GPP standard.
