A New EP-Based Sequential Kalman Smoother: An Application to Faster-Than-Nyquist Signaling

ICC 2025 - IEEE International Conference on Communications
This paper presents a novel turbo-equalizer based on Backward Information Forward Marginals (BIFM) Kalman smoothing. We extend this Kalman smoother with an Expectation Propagation (EP) based message passing strategy to derive an iterative time-domain ...

Signal detection with belief propagation in Faster-than-Nyquist signaling

2017 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2017
Faster-than-Nyquist (FTN) signaling is one of the approaches that improve spectrum efficiency by transmitting symbols faster than the Nyquist rate. However, it suffers from inter-carrier interference (ICI) and inter-block interference (IBI). Thus, the ICI and IBI canceller is needed at a receiver.

Faster-than-Nyquist Single-Carrier MIMO Signaling

2016 IEEE Globecom Workshops (GC Wkshps), 2016
Faster-Than-Nyquist (FTN) signaling is created when a digital communications signal has an occupied bandwidth less than the symbol rate. It has been previously demonstrated that FTN signals can achieve bit error rates near that of full-bandwidth signaling for BPSK and 4-QPSK modulation.

Fundamentals of Faster-than-Nyquist Signaling

2016
This chapter presents the fundamentals of Faster-than- Nyquist (FTN) signaling. As originally introduced, FTN increases the bit-rate in the signaling bandwidth by packing symbols closer in time, at the cost of introducing intersymbol interference (ISI).
