A Novel Solution for Carrier Frequency Offset (CFO) Minimization for Efficient 5G Wireless Communication Using OFDM for Internet of Things (IoT)

In the telecommunications technology, long-term evolution (LTE) will shortly be replaced by 5G wireless connectivity with improved latency, speed and power efficiency. The Internet of things (IoT) is one of the latest developments in 5G technology. IoT ensures low capacity, low cost and loose narrowband synchronization. For easy synchronization of wireless technologies, the cyclic prefix (CP) technique needs to be improved because it is not appropriate for 5G scenarios. When implemented in the OFDM waveform, a separate cyclic prefix (CP) is needed for each symbol. It is not practical for 5G application on narrowband. In this paper, a novel scheme of carrier frequency offset (CFO) estimation technique using cyclic prefix adaptive synchronization (CPAS) algorithm in non-orthogonal multiple access (NOMA) system is proposed.
