An improved orthogonal space-time codes(ISTBC) design method is given in this paper.It can effectively imporve the coding gain,and can overcome the drawback of not being able to transmit with full speed in the cases of multi-antennas(more than 2) and complex signals with original OSTBC.It applies Complex Sphere Decoding(CSD),which is of medium complexity at the receive end.
