Inter-Cell Interference Rejection Based on Ultrawideband Walsh-Domain Wireless Autoencoding
Rodney Martinez Alonso, Cel Thys, Cedric Dehos +2
This paper proposes a novel technique for rejecting partial-in-band inter-cell interference (ICI) in ultrawideband communication systems. We present the design of an end-to-end wir…
