Abstract :
In this paper, we first consider a layered groupwise space-time block coding (GSTBC) scheme for multiple antennas communication systems. A novel list-based decoder for the GSTBC in multiple input single output (MISO) cases is then proposed. The error floor problem associated with the single receive antenna is resolved and, as a result, a near maximum likelihood (ML) performance is obtained. Our proposed scheme can be easily applied to the case of large number of transmit antennas while keeping a reasonably low complexity at the receiver.
