We propose a novel coding scheme, which guarantees full diversity for any number of transmit antennas, provided that few bits of feedback from the receiver to the transmitter are available. This coding scheme is arranged as an extension of orthogonal space-time block coding and preserves its linear decoding complexity. Moreover, it is full rate when the underlying coding method is the Alamouti's scheme. It is shown by computer simulations that the new approach provides SNR improvement, and it is more resilient to feedback errors compared to the antenna selection technique on the basis of same number of feedback bits.
