Spatial modulation of visual responses arises in cortex with active navigation [PDF]
eLife, 2021 During navigation, the visual responses of neurons in mouse primary visual cortex (V1) are modulated by the animal’s spatial position. Here we show that this spatial modulation is similarly present across multiple higher visual areas but negligible in ...

Design guidelines for spatial modulation [PDF]
IEEE Communications Surveys & Tutorials, 2014 A new class of low-complexity, yet energyefficient Multiple-Input Multiple-Output (MIMO) transmission techniques, namely the family of Spatial Modulation (SM) aided MIMOs (SM-MIMO) has emerged.

Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation [PDF]
Sensors, 2023 We propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used.

Vestibular modulation of spatial perception [PDF]
Frontiers in Human Neuroscience, 2013 Vestibular inputs make a key contribution to the own sense of spatial location. While the effects of vestibular stimulation on visuo-spatial processing in neurological patients have been extensively described, the normal contribution of vestibular ...

Device-to-Device Aided Cooperative Relaying Scheme Exploiting Spatial Modulation: An Interference Free Strategy [PDF]
Sensors, 2020 In this paper, a novel interference free dual-hop device-to-device (D2D) aided cooperative relaying strategy (CRS) based on spatial modulation (SM) (termed D2D-CRS-SM) is proposed.

Optical spatial modulation design. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 Visible light communication (VLC) systems are inherently signal-to-noise ratio (SNR) limited due to link budget constraints. One favourable method to overcome this limitation is to focus on the pre-log factors of the channel capacity. Multiple-input multiple-output (MIMO) techniques are therefore a promising avenue of research.

Layered spatial modulation [PDF]
EURASIP Journal on Wireless Communications and Networking, 2018 In this paper, we propose a layered spatial modulation (L-SM) scheme that combines a multi-layered coding scheme with the spatial modulation. At each antenna selection, the number of active transmit antennas equals the number of layers. The proposed L-SM
