Improved Schemes of Differential Spatial Modulation [PDF]

open access: yesIEEE Access, 2021
Differential spatial modulation (DSM) is able to transmit additional data bits without increasing the number of radio-frequency chains and power consumption and also avoids pilot overhead.

Long-Block Differential Spatial Modulation

open access: yesIEEE Access, 2023
Spatial modulation (SM) can transmit additional data bits by selecting antennas and avoids synchronization and interferences among antennas. Differential SM (DSM) is a noncoherent technique of SM, but it is less bandwidth efficient than SM.

Differential Transmission Schemes for Generalized Spatial Modulation [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2021
Differential modulation schemes are very relevant in receivers having power and processing limitations, as these schemes dispense with the need for knowledge of channel coefficients for symbol detection. Spatial modulation (SM) is a scheme used in multi-antenna transmission scenarios where the data is transmitted in the amplitude, phase and spatial ...

Differential spatial modulation for high-rate transmission systems [PDF]

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
This paper introduces a new differential spatial modulation (DSM) scheme which subsumes both the previously introduced DSM and high-rate spatial modulation (HR-SM) for wireless multiple input multiple output (MIMO) transmission. By combining the codeword

Low-Complexity Differential Spatial Modulation Schemes for a Lot of Antennas [PDF]

open access: yesIEEE Access, 2020
Spatial modulation (SM) uses a single antenna for transmission each time to avoid synchronization and interferences among transmitter antennas, and differential SM (DSM) is a kind of SM technique that does not need pilot symbols and channel estimation ...

Secure Transmission for Differential Quadrature Spatial Modulation With Artificial Noise [PDF]

open access: yesIEEE Access, 2019
In this paper, we investigate the secure transmission for differential quadrature spatial modulation (DQSM) with artificial noise (AN) in multiple-input single-output wiretap networks, where a cooperative jammer helps the secure transmission between ...

Generalised differential scheme for spatial modulation systems

open access: yesIET Communications, 2017
Spatial modulation (SM) is an efficient transmission scheme based on multiple‐input multiple‐output systems. SM, by nature, requires coherent detection to achieve optimal error performance. This requires that the receiver has full knowledge of the channel state information (CSI), however, determining the CSI results in an increase ...

Differential Spatial Modulation for APSK in Time-Varying Fading Channels [PDF]

open access: yesIEEE Communications Letters, 2015
We develop a novel differential spatial modulation (DSM) scheme for amplitude phase shift keying (APSK) modulation, which can either improve throughput or performance over DSM for PSK. Then we investigate the impact of time-varying fading on DSM. We find performance degrades if the fading is too fast due to differential detection.

Engineered microtissue systems for identifying the roles of Wnt and YAP signaling in hepatoblast differentiation and organization [PDF]

open access: yesMaterials Today Bio
Liver development requires precise coordination of biochemical and biophysical cues to establish proper zonation and localized cell fate specification. However, there are limited models for studying the interactions between signaling pathways in defined ...
