Conference : ITC-CSCC 
Abstract : In OFDM-based uplink SCMA system, inter-user interference as well as inter carrier interference (ICI) is induced from carrier frequency offset (CFO), which degrade the performances of multi-user detector in uplink SCMA systems. In order to compensate for the CFOs, we propose a novel CFO compensation algorithm for OFDM-based uplink SCMA system. The proposed iterative method consists of amplitudephase compensation, ICI regeneration, and ICI cancellation. The simulation results show that the proposed scheme provides enhances the bit error probability.
