Abstract

Space-time block coding (STBC) can achieve transmit diversity gain and obtain higher coding gain without sacrifice of bandwidth. But the decoding requires accurate channel state information (CSI), which strongly determines the system performance. Independent component analysis (ICA) technique can be used to detect the transmitted signals without channel estimation. In this paper, we study two schemes based on ICA blind detection by exploiting the orthogonality of orthogonal space-time block coding (OSTBC). What is more, some blind algorithms based on channel estimation are used for performance evaluation. Simulation results for Rayleigh fading channels demonstrate that the two proposed schemes achieve significant bit error rate (BER) performance and indicate the optimal separation algorithms suitable for OSTBC system.
