WebJul 10, 2016 · Capacity of block Rayleigh fading channels without CSI. A system with a single antenna at the transmitter and receiver and no channel state information at either is considered. The channel experiences block Rayleigh fading with a coherence time of T0 symbol times and the fading statistics are assumed to be known perfectly. WebIn this paper, we propose a new algorithm for designing unstructured Grassmannian constellations for noncoherent MIMO communications over Rayleigh block-fading channels. The algorithm minimizes the maximum coherence between subspaces, which is shown to be equivalent to the diversity product previously proposed in the literature.
