A Precoding Based Power Domain UFMC Waveform for 5G Multi-Access Edge Computing

Abstract

Multi-Carrier Waveform (MCW) design has become one of the challenging research issue for 5G Multi-Access Edge Computing (MAEC). A large number of different MCWs have been designed and proposed in the literature as an alternative to the conventional Orthogonal Frequency Division Multiplexing (OFDM) waveform. Although, OFDM based waveforms are broadly employed in many real-time systems, but they cannot support the stringent requirements of 5G MAEC. Therefore, more flexible MCWs need to be investigated and designed. Hence, in this paper a new MCW with minimum Peak-to-Average Ratio (PAPR) has been designed and proposed. The proposed MCW is based on precoding and power control of the transmitted Universal Filtered Multi-Carriers (UFMC) signals. Computer simulations in MATLAB® have been carried out to show the performance of proposed precoding based MCW. It is concluded from the computer simulation results that the proposed precoding based waveform outperforms the standard UFMC waveform.
