Second-Order Statistics for STBC Classification Over Amplify-and-Forward Cooperative Systems

open access: yesIEEE Access, 2023
The space-time block code (STBC) classification has recently been recognized as a prominent fundamental tool for the development of smart communication systems, which are applied in both the defense and private sectors.

On the Performance of Space-Time Block Coded Spatial Modulation Transmission for Full-Duplex Relay Networks

open access: yesIEEE Access, 2019
Focusing on the issue that the spatial modulation (SM)-aided full-duplex relaying (SM-FDR) scheme cannot obtain transmit diversity, we present a space-time block coded spatial modulation-based full-duplex relaying (STBC-SM FDR) protocol in this paper. In

Space–time block coded non-orthogonal multiple access for performance enhancement of underwater acoustic sensor networks

open access: yesICT Express, 2022
In this letter, we propose space–time block coded non-orthogonal multiple access (STBC-NOMA) for underwater acoustic sensor networks (UASNs) to improve reliability by exploiting transmit diversity and spectral efficiency.

Blind adaptive receiver for uplink multiuser massive MIMO systems

open access: yesETRI Journal, 2019
Herein, we consider uplink multiuser massive multiple‐input multiple‐output systems when multiple users transmit information symbols to a base station (BS) by applying simple space‐time block coding (STBC).

Improved QC-STBC OFDM system using null interfeence elimination [PDF]

open access: yes, 2013
YesThe quasi-orthogonal space time block coding (QO-STBC) over orthogonal frequency division multiplexing (OFDM) is investigated. Traditionally, QO-STBC does not achieve full diversity since the detection matrix of QO-STBC scheme is not a diagonal matrix.

Omnidirectional Space–Time Block Coding Design for Three-Dimensional Massive MIMO Systems

open access: yesIEEE Access, 2019
Common signals in public channels of cellular systems are usually transmitted omnidirectionally by the base station (BS) to ensure cell-wide coverage.
