Abstract
Circularly pulse-shaped orthogonal frequency division multiplexing (CPS-OFDM) waveform integrated with sparse code multiple access (SCMA) is proposed for 5G and the Factories of the Future (FoF). The physical-layer properties of low out-of-subband emission (OSBE) and low peak-to-average power ratio (PAPR) claimed by CPS-OFDM can be well preserved with the top-down codebook used in SCMA. Simulation results also reveal that the proposed transmission method possesses higher detection reliability and spectral efficiency than those of other existing SCMA-OFDM-based schemes in practical FoF environment.
