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.

A Low Complexity Dispersion Matrix Optimization Scheme for Space-Time Shift Keying
2020 IEEE/CIC International Conference on Communications in China (ICCC), 2020Space- Time Shift Keying (STSK) is a multi-antenna technique, which transmits additional data bits by selecting indices of a pre-designed dispersion matrix set. However, conventional STSK scheme employs a random search scheme to optimize the dispersion matrix set, which requires high computational complexity.

A space-time block code using orthogonal frequency-shift-keying
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005We investigate in this paper an Alamouti-type space-time block code (STBC) using orthogonal M-ary frequency-shift-keying (MFSK). The signal is coherently detected using the channel estimates derived from the unmodulated (or implicit pilot) component of the orthogonal signal.

Space-Time Coding and Processing with Differential Chaos Shift Keying Scheme
2009 IEEE International Conference on Communications, 2009This paper investigates the feasibility to use chaotic communications in MIMO channel. Differential Chaos Shift Keying modulation is chosen as a benchmark and Alamouti space-time code scheme is used for the 2 transmit and 2 receiver antennas wireless system. Based on the evaluation of system performance, improvements are also discussed.

Blind channel estimation of space-time Frequency-Shift Keying
Journal of Electronics (China), 2006The decoupled coherent Maximum Likelihood (ML) detection algorithm presented in this letter can sharply reduce the complexity of the receiver as well as provide better error performance under the precondition that channel should be estimated first. Considering the bandwidth inefficiency of Frequency Shift Keying (FSK), the acquisition of channel state ...

Three-dimensional space-time shift keying with coordinate combination and joint optimisation
2015 IEEE/CIC International Conference on Communications in China (ICCC), 2015In this paper, the concept of three-dimensional (3-D) space-time shift keying (STSK) is introduced, which incorporates 3-D constellations into conventional STSK systems. The new 3-D STSK techniques enjoy better error resilience than their two-dimensional (2-D) counterparts.

Permutation-Aided Space-Time Shift Keying for Indoor Visible Light Communication
2019 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm), 2019An iterative, low-complexity soft-detection (SD) receiver is designed for detecting permutation-aided space-time shift keying (STSK) modulation in an indoor visible light communication (VLC) channel. The indices of the transmitters, which are light emitting diodes (LEDs) are coordinated by antenna matrices using permutations.

Reduced-Complexity Iterative-Detection-Aided Generalized Space-Time Shift Keying
IEEE Transactions on Vehicular Technology, 2012A novel reduced-complexity soft decision (SoD)-aided detector is proposed for the recent concept of space-time shift keying (STSK), where the detector's achievable performance is capable of closely approaching that of the optimal maximum a posteriori (MAP) detector.

Differential space-time coding with offset quadrature phase-shift keying
IEEE 6th Workshop on Signal Processing Advances in Wireless Communications, 2005., 2005Differential space-time coding (DSTC) has been well established as a precoding technique that allows maximum likelihood detection of the received symbols without requiring knowledge of channel state information. This type of detection is useful for highly time-varying channels where the resulting cost of channel estimation is high.

An Artificial Noise assisted secrecy-enhancing scheme for Space–Time Shift Keying systems
Physical Communication, 2019Abstract It is meaningful in practice to explore a secrecy-enhancing Multi-Input-Multi-Output (MIMO) scheme with flexible Radio Frequency (RF) antenna chains as well as low complexity. In this paper, an Artificial Noise (AN) assisted secrecy-enhancing scheme is proposed for the Space–Time Shift Keying (STSK) systems, which has the capability to ...
