Non-binary and linear precoded faster-than-Nyquist signaling

Research output: Contribution to journalArticle

Abstract

Faster than Nyquist (FTN) signaling is an important method of
narrowband coding. The concept is extended here to non
binary signal constellations; these are much more bandwidth efficient
than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is
presented. Precoding FTN transmissions with short linear
filters proves to be an effective way to gain distance. A
Shannon limit to bit error rate is derived that applies for FTN. Tests of an M-algorithm receiver are performed and compared to this limit.
