Abstract: A new diversity scheme for orthogonal frequency division multiplexing/multi-input multi-output (OFDM/MIMO) systems. The new diversity scheme, i.e., turbo layered space-frequency coded OFDM (TLSFC-OFDM), uses the turbo principle with space hopping (SH). The TLSFC-OFDM system uses a successive interference cancellation (SIC) algorithm to reduce the number of iterations. As a result, this scheme reduces computational complexity. Simulation results show that the SIC-based TLSFC-OFDM system outperforms a conventional OFDM/Horizontal Bell Labs Layered Space-Time (H-BLAST) system using a horizontal coding scheme.
