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 ...
