Xin Hu,Zhijun Liu,Xiaofei Yu,Yulong Zhao,Wenhua Chen,Biao Hu,Xuekun Du,Xiang Li,Mohamed Helaoui,Weidong Wang,Fadhel M. Ghannouchi +10 more
TL;DR: A novel behavior model for wideband PAs, using a real-valued time-delay convolutional NN (RVTDCNN), where the coefficient number and computational complexity of the RVTDCNN model are significantly reduced when the memory effects of the PA are increased by using wider signal bandwidths.
