Spatial Frequency Modulation for Semantic Segmentation [PDF]
IEEE Transactions on Pattern Analysis and Machine IntelligenceHigh spatial frequency information, including fine details like textures, significantly contributes to the accuracy of semantic segmentation. However, according to the Nyquist-Shannon Sampling Theorem, high-frequency components are vulnerable to aliasing

Generalized Quadrature Spatial Modulation and its Application to Vehicular Networks With NOMA
IEEE transactions on intelligent transportation systems (Print), 2020 Quadrature spatial modulation (QSM) is recently proposed to increase the spectral efficiency (SE) of SM, which extends the transmitted symbols into in-phase and quadrature domains.

Error probability and capacity analysis of generalised pre-coding aided spatial modulation [PDF]
, 2015 The recently proposed multiple input multiple output (MIMO) transmission scheme termed as generalized pre-coding aided spatial modulation (GPSM) is analyzed, where the key idea is that a particular subset of receive antennas is activated and the specific

Low complexity detection algorithm applied to spatial modulation system
Dianzi Jishu Yingyong, 2019 The paper proposes a low-complexity detection algorithm for spatial modulation. The proposed algorithm reduces the total complexity by reordering the receiving antennas. The algorithm combines the existing A-Star algorithm to layer and sort the receiving

Optimum GSSK Transmission in Massive MIMO Systems Using the Box-LASSO Decoder
IEEE Access, 2022 We propose in this work to employ the Box-LASSO, a variation of the popular LASSO method, as a low-complexity decoder in a massive multiple-input multiple-output (MIMO) wireless communication system.

Transmitter Preprocessing Aided Spatial Modulation for Multiple-Input Multiple-Output Systems
, 2011 This paper proposes and studies a transmitter preprocessing aided spatial modulation (PSM) scheme, which conveys information jointly by a conventional amplitude-phase modulation (APM) and a preprocessing aided space shift keying (pre-SSK) modulation.
