A modified successive interference cancellation (SIC) algorithm for orthogonal frequency division multiplexing (OFDM) system is presented. The presented modified SIC algorithm makes use of an index sequence to avoid the subcarriers re-ordering calculation. Furthermore, by combining the SIC with the conventional zero-forcing (ZF) detection, computation complexity of the presented algorithm can be significantly reduced and meanwhile excellent performance can be maintained.
