In this paper, we investigate the carrier frequency offsets (CFOs) effect on uplink universal filtered multi-carrier-interleave division multiple access (UFMC-IDMA), which has improved robustness against inter-carrier interference (ICI) compared with orthogonal frequency division multiplexing-IDMA (OFDM- IDMA). In particular, a multiuser detection algorithm for uplink UFMC-IDMA which is robust against CFOs is proposed. The proposed algorithm takes the CFOs impact into account in the detection process and iteratively mitigates the combined interference from other users and CFOs. In addition, a corresponding approximation method with reduced complexity is also developed, which omits the interference elements whose values are small. Simulation results validate the superior interference cancellation performance of the proposed algorithm and reveal that the performance loss of the low complexity approximation method is small compare with the proposed algorithm with full calculation.
