Double Antenna-Transitions Spatial Modulation Performance Evaluation Over Nakagami-m Wireless Fading Channels

open access: yesIEEE Access, 2021
Recently, a novel spatial modulation (SM) scheme; termed Mid-symbol Antenna transition (MAT) spatial modulation, was developed to reduce the number of utilized transmitting antennas and improve the average bit error rate (ABER) performance. In this paper,

Spatial Terahertz Modulator [PDF]

open access: yesScientific Reports, 2013
Terahertz (THz) technology is a developing and promising candidate for biological imaging, security inspection and communications, due to the low photon energy, the high transparency and the broad band properties of the THz radiation1,2,3. However, a major encountered bottleneck is lack of efficient devices to manipulate the THz wave, especially to ...

Reward modulates spatial neglect [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 2012
Reward has been shown to affect attention in healthy individuals, but there have been no studies addressing whether reward influences attentional impairments in patients with focal brain damage.Using two novel variants of a widely-used clinical cancellation task, we assessed whether reward modulated impaired attention in 10 individuals with left ...

Microchannel spatial light modulator [PDF]

open access: yesOptics Letters, 1978
A sensitive, high-speed, optically addressed spatial light modulator is being developed for real-time optical dataprocessing applications involving low-level-control light signals. This device is expected to have a sensitivity of better than 10(-3) microJ/cm(2), a framing rate of about 1 kHz, and a spatial resolution of approximately 20 line pairs/mm ...

Spatial Light Modulator Microscopy [PDF]

open access: yesCold Spring Harbor Protocols, 2013
The use of spatial light modulators (SLMs) for two-photon laser microscopy is described. SLM phase modulation can be used to generate nearly any spatiotemporal pattern of light, enabling simultaneous illumination of any number of selected regions of interest.

Parallel Complex Quadrature Spatial Modulation

open access: yesApplied Sciences, 2020
In this paper, we propose a new multiple-input multiple-output (MIMO) transmission scheme, called parallel complex quadrature spatial modulation (PCQSM).

Spatial Modulation for Molecular Communication [PDF]

open access: yesIEEE Transactions on NanoBioscience, 2019
In this paper, we propose an energy-efficient spatial modulation based molecular communication (SM-MC) scheme, in which a transmitted symbol is composed of two parts, i.e., a space derived symbol and a concentration derived symbol. The space symbol is transmitted by embedding the information into the index of a single activated transmitter nanomachine.
