Noncoherent Multiuser Grassmannian Constellations for the Mimo Multiple Access Channel

We consider the design of multiuser constellations for a multiple access channel (MAC) with K users, with M antennas each, that transmit simultaneously to a receiver equipped with N antennas through a Rayleigh block-fading channel, when no channel state information (CSI) is available to either the t…
