In this paper, we extend space-time block coding techniques, originally proposed for point-to-point communication links, to point-to-multipoint communication links. In specific, we combine space-time block coding with single-carrier block transmission DS-CDMA for downlink multi-user MIMO communications. Moreover, we propose a pilot-trained space-time chip equalizer that acts on a per-tone basis in...
Several engineering applications ranging from control to communications have to deal with a clipped Gaussian process, observed in the presence of Additive White Gaussian Noise (AWGN). For such a scenario, we derive in this paper a closed form expression of a Bayesian estimator, which recovers the original undistorted Gaussian process by minimizing the mean square estimation error. In addition, we...
