Abstract :
The Vertical Bell Laboratories Layered Space Time (V-BLAST) detection presented for multiple-input multiple- output (MIMO) system can also be used for orthogonal frequency division multiplexing (OFDM) signal detection, and is referred as the successive interference cancellation (SIC) method. In the paper a refined SIC algorithm is first presented. Then, several less complexity modified SIC algorithms for OFDM signal detection in multi-path fading channel are presented. The presented modified SIC algorithms can significantly reduce the computation complexity of SIC and meanwhile maintain excellent performance.
