FTN Signaling-Aided Space-Time Multi-Mode Index Modulation Systems With a GMP-Based Receiver
In this paper, we propose a faster-than-Nyquist (FTN) signaling-aided space-time multi-mode index modulation (IM) scheme with a low-complexity Gaussian message passing (GMP) based receiver.

Improving OFDM: Multistream faster than Nyquist signaling [PDF]
Mazo's concept of Faster Than Nyquist signaling is extended to pulse trains that modulate adjacent subcarriers, in a manner similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission system achieves the isolated pulse ...

A Survey on Faster-Than-Nyquist Signaling
在数字通信系统中,奈奎斯特准则指出,为了实现无码间干扰的传输,符号速率必须满足奈奎斯特准则。然而1975年Mazo发现在带限加性高斯白噪声信道中,当码元速率超过奈奎斯特速率在25%以内时,信号的归一化最小欧式距离并不会减小,并称为Faster-Than-Nyquist signaling (超奈奎斯特,FTN)。本文首先介绍FTN传输的发展历史,分析FTN系统的Mazo限,并对FTN传输以及奈奎斯特速率下的限制信道容量进行比较。从仿真结果可以看出,当脉冲存在过剩带宽时,FTN传输可以得到比奈奎斯特速率下更高的信道容量。 In digital communication system, the Nyquist criterion states that the symbol rate must ...

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.

PAPR Reduction of Multicarrier Faster-Than-Nyquist Signals With Partial Transmit Sequence
Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient transmission scheme for future communication systems. Similar as general multicarrier signals, the high peak-to-average power ratio (PAPR) is also one of the main drawbacks of MFTN

Faster-Than-Nyquist Non-Orthogonal Frequency-Division Multiplexing for Visible Light Communications
In this paper, we propose a faster-than-Nyquist non-orthogonal frequency-division multiplexing (NOFDM) scheme for visible light communications (VLCs) where the multiplexing/demultiplexing employs the inverse fractional cosine transform (IFrCT)/FrCT ...

Interference cancellation technique for faster‐than‐Nyquist signalling
The faster‐than‐Nyquist (FTN) signalling is a bandwidth‐efficient technology which has drawn attention in the bandwidth‐starved world. However, inter‐symbol interference is introduced by transmitting signals at a higher signalling rate than allowed by the Nyquist criterion.
