Coexistence of filter banks and CP-OFDM: What are the real gains?

Abstract

Abstract-A coexistence scenario between filter bank (FB) based waveforms and legacy Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) is studied. It is shown that studies available on that matter use a wrong metric to rate the interference between the coexisting systems. Specifically, it is shown that even well spectrally localized FB waveforms interfere at a high level with incumbent CP-OFDM receivers. The presented results invalidate a number of studies in the literature, which stated that FB based waveforms could be very efficiently used to insert communications in parts of spectrum left free by incumbent legacy CP-OFDM users.

Improving PAPR performance of filtered OFDM for 5G communications using PTS

“…In 5G, several applications have been introduced to accomplish the new requirements of this market, for example, machine-to-machine (M2M), Internet of things (IoT), and vehicle-to-vehicle (V2V) communications [1]. It requires utilizing new systems in the physical layer (PHY) and the fulfillment of the requirements of the novel applications [2]. Therefore, waveform design is one of the several PHY systems that should be reviewed with regard to the spectral efficiency, relaxed synchronization, low latency, and high reliability.…”
