  • This letter investigates the problem of blind detection of orthogonal space-time block codes (OSTBCs) over a quasi-static flat multiple-input multiple-output Rayleigh fading channel. We first introduce a core iterative least-squares (ILS) algorithm to blindly detect OSTBC signals without the knowledge of channel state information (CSI) at the receiver. This ILS algorithm has low computational complexity but may converge to local optimum, which offers unreliable detection result. Then, in order… CONTINUE READING
