WebMar 11, 2007 · This paper studies the efficient complex matrix inversion for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) and its programmable VLSI implementation are proposed for the inversion of (in this context) large complex matrices with Alamouti sub-blocks. Our … WebFeb 28, 2013 · We provide Arikan polar binary and Alamouti non-binary matrices using the proposed simple inverse and the fast inverse algorithm. It will be seen that the resulting Arikan polar binary and Alamouti non-binary matrices become the FBI Jacket transforms. 3.

"The significance of Alamouti's proposal in 1998 is that it was the first demonstration of a method of encoding which enables full diversity with linear processing at the receiver. Earlier proposals for transmit diversity required processing schemes which scaled exponentially with the number of transmit antennas. See more 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 … See more 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 … See more 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. It was designed for a two-transmit antenna system and has the coding matrix: See more These codes exhibit partial orthogonality and provide only part of the diversity gain mentioned above. An example reported by Hamid Jafarkhani See more 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 achieve the maximum diversity allowed by this criterion. Diversity criterion See more One particularly attractive feature of orthogonal STBCs is that maximum likelihood decoding can be achieved at the receiver with only See more • Multiple-input and multiple-output (MIMO) • Space–time block coding based transmit diversity (STTD) • Space–time code • Space–time trellis code See more " - Alamouti matrix
