Performance of MIMO Systems Using Space Time Block Codes (STBC)
WebKeywords- energy efficiency, LEACH, MIMO, STBC, wireless sensor network I. INTRODUCTION In recent years, virtual MIMO has attracted a growing interest because of its energy efficiency in large field of networks. In virtual MIMO network,a group of sensors cooperate to transmit and receive data[1]. Although the WebNov 9, 2024 · Space-Time block Coding (STBC) is a wireless transmission scheme which exploits multiple antennas at the transmit side without channel state information (CSI) to provide maximum likelihood decoding based on linear processing at the receiver. The receiver can have one or more antenna elements. chaise stokke tripp trapp occasion
MIMO Space-Time Block Coding ( STBC ) : Simulations and Results
WebOct 16, 2008 · Alamouti STBC A simple Space Time Code, suggested by Mr. Siavash M Alamouti in his landmark October 1998 paper – A Simple Transmit Diversity Technique for Wireless Communication, offers a simple method for achieving spatial diversity with two transmit antennas. The scheme is as follows: 1. Consider that we have a transmission … WebApr 1, 2024 · In the past few years, underwater wireless optical communication (UWOC) has become a promising wireless communication technology in the underwater environment. Aiming at the problem formulation of sub-channel correlation enhancement occurring due to the joint impact of underwater link misalignment and turbulence in the process of optical … 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 … 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 papers by Gerard J. Foschini and Michael J. Gans, … 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 … See more One particularly attractive feature of orthogonal STBCs is that maximum likelihood decoding can be achieved at the receiver with only linear processing. In order to consider a … 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'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.
