Based on code division multiple access and amicable orthogonal design, a non-coherent space-time transmission scheme is proposed for multiple-antenna systems, which allows full-diversity communication and is resistant to multiuser interference. Then a differ-ential decorrelative receiver is given for flat Rayleigh fading channels, which decouples not only the detection of different users but also the decoding of different data symbols.
