Title
Overlap-Windowed-DFTs-OFDM with Overlap FFT Filter-Bank for Flexible Uplink Access in 5G and Beyond
Abstract
As IoT (Internet of Things) is one of the most promising applications in 5G and beyond, a new waveform to enable flexible uplink access is strongly required to accommodate various IoT applications. OFDMA (Orthogonal Frequency Division Multiple Access) based approaches such as FBMC (Filter Bank Multi Carrier) are proposed to achieve low ACLP (Adjacent Channel Leakage Power) however, they have some drawbacks such as high PAPR (Peak to Average Power Ratio) and heavy signal processing for channel filtering. This paper proposes overlap-windowed DFTs-OFDM (Discrete Fourier Transform spreading-OFDM) with overlap FFT filter-bank for flexible uplink access in 5G and beyond. The proposed scheme employs overlap windowing at the transmitter side to achieve low ACLP and overlap FFT filter-bank on the receiver side to reduce ACI (Adjacent Channel Interference) even in the case of asynchronous uplink access. This paper also describes performance evaluation results of the proposed scheme.
