Soft-Decoding for Multi-Set Space-Time Shift-Keying mmWave Systems: A Deep Learning Approach
In this paper, we propose a deep learning assisted soft-demodulator for multi-set space-time shift keying (MS-STSK) millimeter wave (mmWave) systems, where we train a neural network (NN) to provide the soft values of the MS-STSK symbol without relying on

Toward Sub‐Terahertz: Space‐Time Coding Metasurface Transmitter for Wideband Wireless Communications
A space‐time coding metasurface (STCM) operating in the sub‐terahertz band to construct new‐architecture wireless communication systems is proposed. Specifically, a programmable STCM is designed with varactor‐diode‐tuned metasurface elements, enabling ...

Joint Time Index Modulation and Receive Antenna Selection for RIS-Aided Communications
In this paper, a novel design, named after time index modulation (TIM) with reconfigurable intelligent surface (RIS)-aided receive antenna selection (RAS), is proposed to improve the spectral efficiency (SE) and the bit error rate (BER) performance.

A novel space-time shift keying and its reduced complexity detector [PDF]
This paper proposes a space-time shift keying (STSK) modulation scheme, which maps the information onto two dimensions, i.e., the temporal and spatial dimensions. For the proposed modulation, a detector with reduced complexity is also proposed. The complexity of proposed detector is reduced with the slight degradation of performance.

Hierarchical Multi-Functional Layered Spatial Modulation
In pursuit of optimal index modulation -aided multiple-input multiple-output (MIMO) systems, where information is implicitly conveyed by relying on the on/off mechanism of the system's components in addition to the classical amplitude, phase, or ...

In this treatise, we present the concept of compressed-sensing (CS)-aided space-time shift keying index modulation (STSK-IM), where a virtual domain orthogonal frequency division multiplexing (OFDM) symbol is divided into Na-sized blocks, which carry K ...

Space-time coded systems with continuous phase frequency shift keying [PDF]
A space-time (ST) trellis encoded scheme with M-ary continuous phase frequency shift keying with a modulation index of 1/M (M-CPFSK) is presented. A ST-M-CPFSK system model that incorporates the Rimoldi decomposition of CPFSK is developed. The Rimoldi decomposition separates the non-memory component of CPFSK from the memory component. The latter can be
