Combining Beamforming and Space-Time BlockCodes with Outer Turbo Codes in Slow RayleighFlat Fading Channels

摘要

Abeamforming technique is combined with thernconventional concatenated scheme of space-time block codesrn(STBC) and turbo codes to consider the imperfect feedback channelrnknowledge. By using beamforming, it is possible to make morerntransmit diversity gain based on the simple predetermined code.rnAt the receiver, the space-time Log-MAP decoding algorithmrnmodified for the combined beamforming, space-time block codesrnand turbo codes system.
