Abstract :
In the IMT2000 DS-CDMA scheme, space time block coding-based transmit antenna diversity (STTD) is adopted as an anti-fading technique. We discuss the mathematical model of the STTD, and deduce an optimum demodulation algorithm for practical implementation. We analyze the performance of the optimum demodulator. Our scheme based on this model is easy to implement and has a good performance
