Abstract
Channel coding is a complicated subject, but vital in cellular communications, which is used for detection and correction of the bit errors caused by various types of noises, interferences. In 3rd generation and 4th Generation (3G and 4G) cellular communications, Turbo codes are predominantly used and currently 3GPP standardization group considering the Low Density Parity Check (LDPC) code in 5G, due to its requirements of 20GB throughput, ultra low latencies and massive Internet of Things. In 5G Communication Filter Bank Multi Carrier (FBMC) wave form is considered for 5G and beyond communication for non-orthogonal communications due to its superior side-lobe suppression characteristics and also no need to use the cyclic prefix, which will save the bandwidth. With FBMC based systems, the Bit Error Rate (BER) performance is still not able to reach the LTE level, which uses Orthogonal Frequency Division Multiplexing (OFDM). In this paper, to achieve a better BER performance, it is proposed to use the LDPC coding with FBMC waveform for 5G communication and was simulated with Keysight SystemVue Software. The BER analysis is performed for both coded and uncoded data transmission for FBMC system with three different modulations: QPSK, 16QAM, 64QAM. The simulated results shows that the LDPC coding with 1/2 code rate is better than other code rates 2/3, 3/4 and 5/6.
