A novel two-antenna hybrid carrier system combining Alamouti space-time block coding is proposed, in which two information symbol vectors are transmitted in single carrier (SC) and multi-carrier (MC) schemes, respectively, from different antennas at the same time. The Weighted Fractional Fourier Transform (WFRFT) is involved at the transmitter. And a new mathematical transformation termed the Weighted Fractional Negative Fourier Transform (WFRNFT) is defined for demodulation. The simulation results show that the cross-modulation system has better bit error rate (BER) performance than the existing SC and MC Alamouti systems.
