Multiuser space-time block coded MIMO with downlink precoding
Space–time block coding is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data transfer. The fact that the transmitted signal must traverse a … Zobraziť viac Most work on wireless communications until the early 1990s had focused on having an antenna array at only one end of the wireless link — usually at the receiver. Seminal papers by Gerard J. Foschini and Michael J. Gans, … Zobraziť viac The design of STBCs is based on the so-called diversity criterion derived by Tarokh et al. in their earlier paper on space–time trellis codes. Orthogonal STBCs can be shown to … Zobraziť viac One particularly attractive feature of orthogonal STBCs is that maximum likelihood decoding can be achieved at the receiver with only Zobraziť viac • Multiple-input and multiple-output (MIMO) • Space–time block coding based transmit diversity (STTD) • Space–time code • Space–time trellis code Zobraziť viac Alamouti's code Siavash Alamouti invented the simplest of all the STBCs in 1998, although he did not coin the term "space–time block code" himself.
