An 0.8-mm$^2$ 9.6-mW Iterative Decoder for Faster-Than-Nyquist and Orthogonal Signaling Multicarrier Systems in 65-nm CMOS

This paper presents an iterative decoder for faster-than-Nyquist (FTN) and orthogonal signaling multi-carrier systems. FTN signaling is a method of improving bandwidth efficiency at the expense of higher processing complexity in the transceiver. The decoder can switch between orthogonal and FTN signaling modes and exploits channel properties to improve… (More)
