Unitary Space-Time Modulation Based on Coherent Codes

open access: yesSensors, 2022
This paper analyzes the relationship between pilot symbol-assisted modulation (PSAM) and unitary space-time modulation (USTM). In particular, we present a map that transforms any PSAM into a USTM and vice versa.

Single-Carrier Rotation-Interleaved Space-Time Code for Frequency-Selective Fading Channels

open access: yesApplied Sciences, 2022
A novel single-carrier-based space-time code construction scheme to exploit the advantages of a frequency-selective fading channel is investigated in this paper.

Construction method of space-time code in MIMO-VLC system [PDF]

open access: yesMATEC Web of Conferences, 2021
In the recent years, the design of any order of space-time block code did not appear in the previous. In this paper, we investigate the criterion that how to design the space-time block code in Multiple input multiple output(MIMO) visible light ...

Constant Weight Space-Time Codes for Dimmable MIMO-VLC Systems

open access: yesIEEE Photonics Journal, 2020
Visible light communication(VLC), which combines communication and illumination, is regarded as a potential wireless communication. For illumination requirements of VLC systems, dimming control is a significant function.

Space-Time Frequency Block Codes in LTE-DSRC Hybrid Vehicular Networks

open access: yesInternational Journal of Technology, 2022
In vehicular communication systems, Dedicated Short Range Communication (DSRC) is said to provide fast communication and high security between vehicles. Simultaneously, Long-Term Evolution (LTE) is used due to its high bandwidth, low latency, and high

Performance Evaluation of Spatial Modulation and QOSTBC for MIMO Systems

open access: yesEAI Endorsed Transactions on Mobile Communications and Applications, 2015
Multiple-input multiple-output (MIMO) systems require simplified architectures that can maximize design parameters without sacrificing system performance. Such architectures may be used in a transmitter or a receiver.

Space-Time Radar Waveforms: Circulating Codes

open access: yesJournal of Electrical and Computer Engineering, 2013
This paper describes a concept of the circulating codes covering the whole class of the space-time codes. The circulating codes do not narrow the radiated pattern of the antenna array, thus providing a wide angular coverage, possibly tunable.

Super-Orthogonal Block Codes with Multichannel Equalisation and OFDM in Frequency Selective Fading

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
Super-orthogonal block codes in space-time domain (i.e., Super-orthogonal space-time trellis codes (SOSTTCs)) were initially designed for frequency nonselective (FNS) channels but in frequency selective (FS) channels these super-orthogonal block codes ...

New space-time block codes from spectral norm.

open access: yesPLoS ONE, 2019
Current research proposes a natural environment for space-time codes and a new design criterion is obtained for space-time block codes in multi-antenna communication channels.

Full-Diversity Space-Time Error Correcting Codes with Low-Complexity Receivers

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
We propose an explicit construction of full-diversity space-time block codes, under the constraint of an error correction capability. Furthermore, these codes are constructed in order to be suitable for a serial concatenation with an outer linear ...
