In this paper, we consider a slow-fading n<inf>t</inf> &#x00D7;n<inf>r</inf> multiple-input multiple-output (MIMO) channel subjected to block fading. Reliability (in terms of achieved diversity order) and rate (in number of symbols transmitted per channel use) are of interest in such channels. We propose a new precoding scheme which achieves both full(More)
— In this paper, we propose new non-coherent space-time block code (STBC) designs, which achieve full transmit diversity as well as high rates. We first present a search procedure to generate full-diversity non-coherent unitary space-time code-books for any number of transmit antennas (nt) and time slots (T ≥ 2nt), using radial coordinates of points lying(More)
