Abstract-The transmitter of multicarrier faster-thanNyquist Signaling is a promising direction. In this paper, the bit and power allocation problem is discussed for the multicarrier FTN environment, with the aim to maximum mutual information while guarantee the practicality. An improved spectral shaping scheme with integer bit constraint is proposed for the transmitter. It is based on the modified iterative water-filling and greedy algorithm revised for our scenario. Correspondingly, there are two processes for the scheme called iterative power allocation and discrete bit replenishment. With the benefit of improved method, integer bits can be ensured for each subcarrier at the cost of a little mutual information loss. This is confirmed by simulation and numerical results.

The Evolution of Faster-Than-Nyquist Signaling

The fifty-year progress of faster-than-Nyquist (FTN) signaling is surveyed. FTN signaling exploits non-orthogonal dense symbol packing in the time domain for the sake of increasing the data rate attained. After reviewing the system models of both the conventional Nyquist-based and FTN signaling transceivers, we survey the evolution of FTN techniques, including their low-complexity detection and channel estimation. Furthermore, in addition to the classic FTN signaling philosophy, we introduce the recent frequency-domain filtering and precoding aided schemes. When relying on precoding, the information rate of FTN signaling becomes related to the eigenvalues of an FTN-specific intersymbol interference matrix, which provides a unified framework for the associated information-theoretic analysis and simplifies the associated power allocation specifically designed for increasing the information rate attained. We show that the FTN signaling scheme combined with bespoke power allocation employing a realistic raised-cosine shaping filter achieves the Shannon capacity associated with ideal rectangular shaping filters.
