Space-Time Shift Keying Aided OTFS Modulation for Orthogonal Multiple Access [PDF]
IEEE Transactions on Communications, 2023 Space-time shift keying-aided orthogonal time frequency space modulation-based multiple access (STSK-OTFS-MA) is proposed for reliable uplink transmission in high-Doppler scenarios. As a beneficial feature of our STSK-OTFS-MA system, extra information bits are mapped onto the indices of the active dispersion matrices, which allows the system to enjoy ...

Dispersion Matrix Optimization for Space-Time Shift Keying
IEEE Communications Letters, 2011In this Letter, we introduce an efficient dispersion matrix optimization technique for the recent concept of Space Time Shift Keying (STSK). By exploiting the STSK-specific signal structure relying on the dispersion-matrix activation, rather than the classic spatial multiplexing, computational complexity imposed by the system optimization is reduced by

“Near-Perfect” Finite-Cardinality Generalized Space-Time Shift Keying [PDF]
IEEE Journal on Selected Areas in Communications, 2019 Two decades of full-diversity high-rate MIMO research has created perfect Space-Time Block Codes (STBCs), including the Golden code. However, the major stumbling block of their wide-spread employment is their limited energy-efficiency. On one hand, the superposition of their signals results in a high Peak-to-Average Power Ratio (PAPR).

IEEE Transactions on Wireless Communications, 2011 In this paper, motivated by the recent concept of Spatial Modulation (SM), we propose a novel Generalized Space-Time Shift Keying (G-STSK) architecture, which acts as a unified Multiple-Input Multiple-Output (MIMO) framework.

Iterative soft-detection of Space-Time-Frequency Shift Keying [PDF]
2012 IEEE International Conference on Communications (ICC), 2012 Inspired by the concept of Space-Time Shift Keying (STSK), the further evolved philosophy of Space-Time-Frequency Shift Keying (STFSK) was proposed for Multiple-Input-Multiple-Output (MIMO) wireless communications, where a beneficial diversity gain may be gleaned from three different domains, namely the space-, time- and frequency-domain. In this paper

Space–Time Frequency-Shift Keying
IEEE Transactions on Communications, 2004Frequency-shift keying (FSK) is a popular modulation scheme in power-limited communication links. This paper introduces space-time FSK (ST-FSK), which does not require any channel state information at the transmitter and the receiver, as in conventional noncoherent FSK. ST-FSK can be viewed as a special unitary ST modulation design. However, ST-FSK has

Coherent and Differential Space-Time Shift Keying: A Dispersion Matrix Approach
IEEE Transactions on Communications, 2010 Motivated by the recent concept of Spatial Modulation (SM), we propose a novel Space-Time Shift Keying (STSK) modulation scheme for Multiple-Input Multiple-Output (MIMO) communication systems, where the concept of SM is extended to include both the space

Coherent Versus Non-Coherent Decode-and-Forward Relaying Aided Cooperative Space-Time Shift Keying
IEEE Transactions on Communications, 2011 Motivated by the recent concept of Space-Time Shift Keying (STSK), we propose a novel cooperative STSK family, which is capable of achieving a flexible rate-diversity tradeoff, in the context of cooperative space-time transmissions. More specifically, we

Sphere decoding for generalized space-time shift keying
2014 4th IEEE International Conference on Information Science and Technology, 2014In this paper, the sphere decoding (SD) detector for the generalized space-time shift keying (G-STSK) scheme is developed to reduce the computational complexity of the optimal detector. The proposed SD detector consists of a series of SD algorithms with each one associated with an activated dispersion matrix pattern.

Space-time coded ternary phase shift keying
Fourth International Conference on Information, Communications and Signal Processing, 2003 and the Fourth Pacific Rim Conference on Multimedia. Proceedings of the 2003 Joint, 2004This paper addresses the space-time coding (STC) in ternary phase shift keying (TPSK) for highly reliable wireless communications. TPSK has not been focused upon until now, although it has theoretically excellent features for mobile communication systems, that is, splendid error rate characteristics and minimum amplitude fluctuation among all of the ...
