Constrained Capacity Analysis for Faster-than-Nyquist Signaling
Zichao Zhang, Melda Yuksel, Gokhan M. Guvensen, Halim Yanikomeroglu
This paper studies the constrained-capacity for precoded faster-than-Nyquist (FTN) signaling with finite-alphabet inputs. Despite the promise of accelerated transmission, the fundamental rate limit of precoded FTN signaling under practical finite-alphabet constraints remains uncl…
