The combination of space-time codes and a closed loop transmission diversity technique is currently receiving a lot of attention since it allows one to improve the performance of wireless communications channels. This paper proposes a simple closed loop transmission diversity technique to improve further the performance of the channels through proposing a structure of feedback information in order to reduce the time required for processing the feedback information at the transmitter. Calculations and simulations show that our technique performs especially well when it is combined with the Alamouti code.
