A novel BLAST transceiver named turbo-like BLAST(TLBLAST) for MIMO communications is proposed,which combines the characteristics of HBLAST and VBLAST with the structure of turbo encoder. The high data rate transmission can be implemented and in each transmitted antenna,different encode schemes can be used to supply different protection levels. The system performance is improved effectively through serially concatenating a soft input soft output(SISO) detector and decoder by iterative process with comparable complexity of VBLAST. Simulation results show that the performance of TLBLAST is better than HBLAST and VBLAST in Rayleigh flat fading channels.

The high data rate transmission can be implemented and in each transmitted antenna, different encode schemes can be used to supply different protection levels. The system performance is improved effectively through serially concatenating a soft input soft output (SISO) detector and decoder by iterative process with more complexity complexity of VBLAST. Simulation results show that the performance of TLBLAST is better than HBLAST and VBLAST in Rayleigh flat fading channels.
