Implementation and Study of Universal Filtered Multicarrier (UFMC) Communication under Carrier Frequency Offset For 5 G

OFDM is a matured technology and applied in various wireless standards. However they are not suitable for Uplink and this technology is replaced by SC FDMA in 4G standards. Similarly Universal Filtered Multicarrier Communication (UFMC) is another suitable technology for Multi user Uplink and for applications like cognitive radio. UFMC is a new, non-orthogonal, waveform designed by Alcatel Lucent Labs which provide a much more efficient way of enabling networks to serve both broadband users and very narrowband “short data” devices such as any embedded sensor or M2M module. In UFMC the filtering of waveform is done on a group of subcarriers. In OFDM it is done on the whole subcarriers together. This reduces the side lobe levels, inters carrier interference (ICI) and requires reduced filter length. Moreover Internet-of-Things where Machine-Machine communication and applications where very tight response in time requirements are needed, OFDM miserably fails. We examine impact of carrier frequency offset on the performance of the proposed scheme and compare the results performance of cyclic prefix based orthogonal frequency division multiplexing(CP-OFDM) system.-
