Differential Quadrature Spatial Modulation
IEEE Transactions on Communications, 2017Quadrature spatial modulation (QSM) is a recent multiple input multiple output transmission scheme that attracted significant research interest. QSM expands the spatial constellation diagram of spatial modulation (SM) to enhance the overall spectral efficiency while retaining all SM inherent advantages.

Differential Spatial Modulation
IEEE Transactions on Vehicular Technology, 2014Spatial modulation (SM) is a newly emerging multiple-input–multiple-output technique that activates only a single antenna for transmission at any time instant and uses the index of the active antenna as an additional information-carrying mechanism. However, by its nature, SM decoding is coherent in that channel state information (CSI) is required at ...

Low-Complexity Differential Spatial Modulation
IEEE Wireless Communications Letters, 2019Differential spatial modulation (DSM) is a multi-antenna technique which transmits additional data bits by selecting indexes of antennas and avoids pilot overhead. However, DSM is complicated in two aspects and we aim to reduce the complexity of DSM in this letter.

Differential Optical Spatial Modulation Over Atmospheric Turbulence
IEEE Journal on Selected Topics in Signal Processing, 2019Optical spatial modulation (OSM) is a multiple-input–multiple-output technique wherein the overall information is transferred through spatial and signal domains simultaneously. A problem in OSM is the necessity for channel state information at receiver (CSIR) that is obtained by complex channel estimation procedure.

A Low-Complexity Detection Scheme for Differential Spatial Modulation
IEEE Communications Letters, 2015Differential spatial modulation (DSM), which does not require the channel state information at the receiver, is an attractive alternative to its coherent counterpart. The optimal maximum-likelihood (ML) detector of the DSM system employs the classic block-by-block method for jointly detecting the activated antenna matrix (AM) and the modulation symbols,

A Low-Complexity Near-ML Differential Spatial Modulation Detector
IEEE Signal Processing Letters, 2015Differential spatial modulation (DSM) is a newly-emerging differential scheme tailored to the spatial modulation technique, which selects only one among a group of antennas for transmission at any time instant. DSM, however, gives rise to prohibitive search complexity when the number of transmit antennas is large.

Performance Analysis of Differential Spatial Modulation with Two Transmit Antennas
IEEE Communications Letters, 2014Differential spatial modulation (DSM) is favorable in practice since it can offer a better tradeoff between reception reliability and system complexity in comparison with coherent spatial modulation (SM). In this letter, the bit error probability (BEP) performance of a point-to-point communication system, in which DSM is adopted at a transmitter ...
