Analytic investigation into the statistical characteristics of the interference due to non-orthogonal time–frequency signaling

Engineering Science and Technology, an International Journal, 2017
The statistical characteristics of non-truncated Intersymbol and Interchannel Interference (ISI/ICI) due to Non-Orthogonal Time-Frequency Signaling (NOTFS) are analytically investigated. The Gaussianity of ISI/ICI is formally discussed in general.

Novel Intersymbol Interference Cancellation Scheme to Enable Parallel Computational and High-Performance Faster-Than-Nyquist Signaling

IEEE Access, 2017
In this paper, we deal with the intersymbol interference (ISI) cancellation problem induced by the faster-than-Nyquist (FTN) signaling. In the traditional FTN signaling, the detection delay at the receiver depends on the number of states of the ISI ...

A first encounter with faster-than-Nyquist signaling on the MIMO channel

, 2007
In this paper we investigate MIMO systems where faster-than-Nyquist (FTN) signaling is used as modulation. On the AWGN channel, the main characteristic of FTN is the so called Mazo limit; it is possible to signal considerably faster than conventional ...
