  • Vertical Bell Labs Layered Space Time (V-BLAST) scheme improves greatly system channel capacity, however multi-transmit antennas introduce space interference, which degrades sharply BER (FER) performance. In order to overcome effectively the space interference, an iterative ordered Zero-Forcing Hybird Interference Cancellation (ZF-HIC) algorithm is adopted. Compared to conventional Zero-Forcing Serial Interference Cancellation (ZF-SIC) algortithm, ZF-HIC provides better BER and FER performance with a lower computational complexity. Soft-information after ZF-HIC detector is sent to Turbo iterative decoding and the resulting hard decision-information can be sent back to V-BLAST detector again to further update and improve the performance of ZF-HIC detector. So, the Turbo V-BLAST has the double-iterated concatenated decoding structure. The simulation results are presented to verify its advantages.
