Performance analysis of generalized orthogonal code index modulation system

Dianxin kexue, 2022
In order to improve the transmission efficiency of the code index modulation (CIM) system, a generalized orthogonal code index modulation (GQCIM) system with lower complexity was proposed, which was a single input single output (SISO) system.CIM system ...

Generalized Spatial Modulation in Highly Correlated Channels [PDF]

2019 IEEE 30th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC Workshops), 2019
Generalized spatial modulation (GSM) is a promising technique that can highly increase the spectral efficiency for ultra-high data rate systems. However, its performance degrades in highly correlated channels such as those in the millimeter wave (mmWave) and sub-Terahertz (sub-THz) bands.

Complex Hadamard Matrix-Aided Generalized Space Shift Keying Modulation

IEEE Access, 2017
In this paper, we present a complex Hadamard matrix-aided generalized space shift keying (HSSK) modulation scheme, which introduces complex-Hadamard-based signal vectors at the transmitter to provide higher spectrum efficiency than generalized space ...

Enhanced spatial modulation with generalized antenna selection in MISO channels

IET Communications, 2021
Here, an enhanced spatial modulation with generalized antenna selection (ESM‐GAS) for multiple‐input single‐output systems is proposed. Unlike the conventional SM systems, in ESM‐GAS, the number of active antennas is not fixed, but varies from only one ...

Generalized Polarization–Spatial Modulation With Multimode Transmission [PDF]

IEEE Internet of Things Journal
Polarization-spatial modulation (PSM) has been recently proposed to improve the system performance and energy efficiency of the conventional polarization modulation (PM) by activating only a single dual-polarized (DP) antenna for signal transmission.

A DNN Architecture for the Detection of Generalized Spatial Modulation Signals [PDF]

IEEE Communications Letters, 2020
In this letter, we consider the problem of signal detection in generalized spatial modulation (GSM) using deep neural networks (DNN). We propose a novel modularized DNN architecture that uses small sub-DNNs to detect the active antennas and complex modulation symbols, instead of using a single large DNN to jointly detect the active antennas and ...
