Transmit Diversity over a Frequency Selective Fading Channel : Turbo Deflation and Turbo Decoding

In this article, we introduce a blind MIMO communication scheme allowing the transmission over a frequency selective channel based on the turbo deflation described in [1]. Our proposed method is based on an iterative receiver. We incorporate an error correcting code in our method of source separation. Our new method consists simply in combining our initial method and a turbo decoder. We show that our procedure improves performances. Our scheme uses 2 transmit antennas and K (K ges 2) received antennas. This kind of blind system is well suited for underwater communications.
