Modified Successive Interference Cancellation for OFDM Signal Detection?

[[abstract]]A modified successive interference cancellation (SIC) algorithm for orthogonal frequency division multiplexing (OFDM) system is presented. The presented modified SIC algorithm makes use of,m 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.[[note]]SC
