Circular shifted transmit diversity [PDF]

open access: yesWireless Communications and Mobile Computing, 2004
AbstractThree design requirements of space‐time block code, full diversity order, full data rate and orthogonality, cannot be achieved simultaneously when the number of transmit antenna is more than two. In this paper, we propose a transmit diversity scheme—circular shifted transmit diversity (CSTD).

Nonbinary LDPC-Coded Sphere-Packed Transmit Diversity [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2008
A recently proposed space-time block-coding (STBC) signal construction method that combines orthogonal design with sphere packing (SP) (referred to here as STBC-SP) has shown useful performance improvements over Alamouti's conventional orthogonal design.

Enhancing MIMO Capacity Through Space-Time Coding: Analysis And Design Framework

open access: yesJournal of Informatics and Web Engineering, 2023
Space-time coding combines time and space to generate codewords, transmitting signals in both time and space domains. This leads to not only diversity and coding gains but also reduces the impact of multipath fading, resulting in high spectral efficiency.

Analysis of Distributed Transmit Diversity with Outdated Diversity Weights [PDF]

open access: yesMobile Information Systems, 2017
Distributed transmit diversity (DTD) technique that combines cooperative communications and diversity techniques is a suitable solution in 5th-generation (5G) systems. In this paper, we investigate the effect of receiver phase compensation (RPC) on the performance of DTD. We introduce new expressions for the average error rate of DTD in the presence of

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

Capacity Analysis of Channel Inversion Using Space-Time Block Coding with Transmit Power Control

open access: yesElektronika ir Elektrotechnika, 2022
In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branch ...

Wireless power transfer with transmit diversity [PDF]

open access: yesF1000Research, 2021
Background: Wireless power transfer is important for energizing and recharging the Internet-of-Things (IoT) cordlessly. Harnessing energy effectively from radio waves has become a crucial task. It is known that diversities at the transmitting antenna and waves (i.e.
