Adaptive decoding for space time codes with imperfect channel estimation, using the bootstrap algorithm

Space time coding is a powerful technique to exploit transmitter diversity. Nevertheless, to enjoy its full potential performance, a perfect knowledge of the channel state information should be available at the receiver. Since even small channel estimation error results in severe performance lose, a long, rate consuming training sequences should be used to minimize these estimation errors. Hence, presenting an undesired tradeoff between rate and performance. Applying the ”bootstrap” algorithm; an adaptive decoder, can mitigate the effect of estimation errors, hence enables a way out of this deadlock, by achieving high performance transmission while reducing the required length of the training sequences.
