Clipping Noise-Aided Message Passing Algorithm for SCMA-OFDM System

Sparse code multiple access combined with orthogonal frequency division multiplexing (SCMA-OFDM) is a promising wireless air-interface technology for fifth generation (5G) networks to support massive connections. The existing problem for SCMA-OFDM system is that the peak-to-average power ratio (PAPR...
