Digital communications using multi-input multi-output (MIMO) has recently emerged as one of the most significant technical breakthroughs in modern communications  as they offer remarkable spectral efficiency. Among many types of space-time codes, the layered space-time codes (LST)  offer a multiplexing gain of ntau (number of transmit antennas) rather than diversity gain offered by space-time block and trellis codes -.. Turbo codes  are considered novel and revolutionary error-control coding technique because they offer a remarkable performance using an iterative process at the receiver. This iterative process uses a soft input soft-output decoder such as maximum a posteriori probability (MAP)  decoder or soft output Viterbi algorithm (SOVA),. In this paper it is proposed to use turbo codes in conjunction with different LST architectures using parallel interference canceller (PIC) iterative receiver. MAP algorithm is used as the soft-input soft-output decoder. Simulation results show a great improvement compared to non-turbo LST systems.
