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.

Spatial Modulation for Beyond 5G Communications: Capacity Calculation and Link Adaptation

open access: yesProceedings, 2019
Spatial Modulation (SM) is a candidate modulation scheme for beyond 5G communications systems due to its reduced hardware complexity and good trade-off between energy and spectral efficiency.

Spatial modulation of fast antenna switch

open access: yesDianzi Jishu Yingyong, 2018
A fast switching spatial modulation scheme is proposed to improve the secrecy performance of the spatial modulation signal. The signal is a space-spread-spectrum signal associated with the channel information because of fast antenna switch.

A Survey on Spatial Modulation OFDM: Optimal Detection and Performance Analysis

open access: yesENP Engineering Science Journal, 2023
Spatial modulation is a novel modulation scheme that aims to acquire a trade-off between the two adverse purposes in wireless communications, namely the improvements of data rate and data reliability, by adjusting the operational transmit antenna index ...

Detection of Spatial-Modulated Signals in the Presence of CSI Uncertainty and Spatially- and Time-Selective Fading

open access: yesIEEE Access, 2022
Although the channel state information (CSI) is never perfect and varies in time, most studies on spatial modulation (SM) systems assume perfectly known CSI and time-invariant channel.

An Intelligent Target Feature Recognition Method Based on Multi-mode OAM Beams

open access: yesLeida xuebao, 2021
Target detection based on space modulation requires a large number of test modes with space-time independence. The Orbital Angular Momentum (OAM) beams are orthogonal to each other and have infinite modes.
