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 ...

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication
, 2015 In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses $N_t$ light emitting diodes (LED), but activates only $N_a$ of them at a given time.

Focusing light through scattering media by polarization modulation based generalized digital optical phase conjugation [PDF]
, 2017 Optical scattering prevents light from being focused through thick biological tissue at depths greater than ∼1 mm. To break this optical diffusion limit, digital optical phase conjugation (DOPC) based wavefront shaping techniques are being actively ...
