Evaluation of Waveforms for Mobile Radio Communications Above 6 GHz

This paper provides a high level comparison of several multi-carrier and single-carrier waveforms based on the evaluations performed in mmMAGIC project. The waveforms are assessed for performance indicators that are relevant to mobile radio communication above 6 GHz, especially the millimeter wave frequencies. The evaluations are performed in mmMAGIC waveform simulators under common assumptions on carrier frequencies, waveform parameters, channel and impairment models. The evaluation results reveal that OFDM is attractive for above 6 GHz communication. For above 30 GHz communication, DFTS-OFDM and OFDM with PAPR reduction are promising options.Moreover, some potential enhancements to OFDM(use of window/pulse shape, subband filters, unique word, zero tailing), parametrization of FBMC, and constrained envelop continuous phase modulation for above 6 GHz communication have been discussed.
