Abstract :
Space-time coding schemes are designed to achieve potentially high capacity offered in MIMO Rayleigh fading channels by exploiting the benefits of spatial and temporal diversity. We propose recursive space-time trellis codes for high bandwidth efficient 8PSK and 16QAM space-time turbo coded modulation. The proposed scheme was designed to preserve the maximum transmit diversity gain but simultaneously enhance the coding gain as compared to Tarokh et al. space-time trellis codes. Puncturing the outputs of component codes enabled a considerable improvement in power efficiency to come with no cost in high bandwidth efficiency. Good performance was reported even with extremely short input information frames
