Fig. 6From: A novel deep learning automatic modulation classifier with fusion of multichannel information using GRUPerformance comparison for FGDNN with and without GRU layers, without CNN. This figure presents performance comparison for FGDNN with and without GRU layers, without CNN. It shows that FGDNN with GRU layers outperforms the others. The FGDNN yields almost 2Â dB gain over the one without CNN layersBack to article page
