Orthogonal frequency division multiplexing (OFDM); Filtered-OFDM; Fifth generation (5G) wireless system.Abstract
In this paper, the authors propose alternative filters to improve the spectral properties of the filtered orthogonal frequency division multiplexing (filtered-OFDM) candidate waveform for new wireless systems (fifth generation (5G) and next generation). The effectiveness of the proposed alternative filters is validated through extensive simulations and experiments in the 5G scenarios at waveform 2K. The results show that the alternative filters can improve the spectral containment capability of a filtered-OFDM signal by more than 100 dB when compared to an OFDM signal. The proposed filters meet the optimization requirements as well as the ongoing or planned standardization.
