%X Combined beamforming with Alamouti space-time block coding may not be optimal under many situations since it only provides two equal power loading beams. A new scheme which combines beamforming with space-time block coding is proposed in this paper. The number of beams the new scheme provides is determined by the channel correlation matrix eigenvalues, and is not more than the number of transmit antennas. Condition on the number of space-time block coding transmit antennas is the same as the number of beams, the new scheme combines beamforming with space-time block coding of any code rate. Ganss-Chebyshev quadrature is used to calculate the symbol error rate of the new scheme for linear modulation and a simple numerical method is derived. The new scheme could improve the performance dramatically by providing diversity gain and beamforming gain simultaneously.
