A Study on the Performance Metrics of the Universal Filtered Multi Carrier Waveforms for 5G

Abstract

Over the past few years, wireless communication has contributed to the economic and social growth of both developed and developing countries. Cellular networks have become an essential part of the daily lives of billions of people worldwide, a trend that is expected to continue. Orthogonal Frequency division Multiplexing (OFDM) is a modulation technique used in 4G. OFDM have some drawbacks like side band leakages and high Peak to Average Power ratio (PAPR) issues. With the advent of Internet of Things (IOT) and the move towards user centric processing makes the OFDM techniques more unfeasible. On the other hand, various multicarrier techniques are found in the literature, but each of them have major drawbacks. In this study we have introduced Universal Filtered Multi Carrier (UFMC) which is a modulation technique that can be adapted with fifth generation (5G) of mobile networks. We have compared peak to average power ratio (PAPR) of UFMC and OFMD. The simulation results show that, UFMC demonstrated significantly lower PAPR for QAM 16 and QAM 64. However, OFDM remains good choice when the Modulation technique is QAM 4 and QAM 256. This marks UFMC is advantageous over OFMD in terms of application for 5G communications.
