Multiple-antenna techniques for wireless communications - a comprehensive literature survey (2009, methodology): “SD Diversity reception (MRC) [4] Rx Rx N low DIV Alamouti’s scheme [2]/OSTBCs [55] Tx (Rx optional) —- ” —- N low DIV Delay diversity [51], [52] —- ” ——- ” —- N moderate/high DIV STTCs [3] —- ” ——- ” —- N high DIV & COD Quasi-orthogonal STBCs [71] —- ” ——- ” —- N low DIV Super-orthogonal STTCs [78],”
Single-carrier frequency domain equalization (2008, methodology): “Addressing transmission rate efficiency, quasi-orthogonal STBCs (QO-STBCs) [ 43 ] were proposed to provide a partial diversity of 2 at rate 1 for four transmit antennas and can be easily generalized for 2 n (n > 2) transmit antennas.”
Space-time diversity systems based on linear constellation precoding (2003, methodology): “The decoding of quasi-orthogonal ST in [16] was implemented.”
On channel estimation and optimal training design for amplify and forward relay networks (2008, background): “The 4×4 and 8×8 QOSTC have been proposed in [ 26 ] and [27], respectively, where certain constellation rotation should be conducted to ensure the transmission with full-rate and full diversity.”
A robust maximin approach for MIMO communications with imperfect channel state information based on convex optimization (2006, background): “1 The application of quasi-orthogonal space–time block codes [43] is not possible since they lead to nonlinear ML detectors whose performance cannot be directly measured by the SNR.”
Multifunctional reconfigurable MEMS integrated antennas for adaptive MIMO systems (2004, methodology): “For more than two antennas, recently developed quasi-orthogonal STBCs are used to achieve full rate and full diversity at the expense of a slight increase in decoding complexity [5].”
Single-symbol maximum likelihood decodable linear STBCs (2006, background): “Starting fro m Alamouti [12], several authors have studied Space-Time Blo ck Codes (STBCs) obtained from Orthogonal Designs (ODs) and their variations that offer fast decoding (single-symb ol decoding or double-symbol decoding) over quasi-static fad ing channels [9]-[20], [21]-[27].”
From theory to practice: an overview of MIMO space-time coded wireless systems (2003, background): “The extension of the above STBC to more than two TX antennas was studied in [62] and [67]–[69].”
MIMO Wireless Linear Precoding (2007, methodology): “SIMULATION SETUP The simulation system has four transmit and two receive antennas and employs the quasiorthogonal STBC [40], [41].”
Full-diversity, high-rate space-time block codes from division algebras (2003, background): “A scheme that trades diversity for simpler ML decoding (double-symbol decoding) is presented in [23] for four and eight antennas and with certain restrictions on the signal constellation that the variables take values from it has been shown by several authors [24]–[29] that rate and/or diversity can”
