Generalized multiuser orthogonal space-division multiplexing [PDF]
IEEE Transactions on Wireless Communications, 2004 —This paper addresses the problem of performing orthogonal space-division multiplexing (OSDM) for downlink, point-to-multipoint communications when multiple antennas are utilized at the base station (BS) and (optionally) all mobile stations (MS).

Space-division multiplexing optical coherence tomography. [PDF]
Opt Express, 2013 High speed, high resolution and high sensitivity are desirable for optical coherence tomography (OCT). Here, we demonstrate a space-division multiplexing (SDM) technology that translates long coherence length of a commercially available wavelength tunable laser into high OCT imaging speed.
