Superposition Coded Modulation Based Faster‐Than‐Nyquist Signaling
Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 A structure of faster‐than‐Nyquist (FTN) signaling combined with superposition coded modulation (SCM) is considered. The so‐called FTN‐SCM structure is able to achieve the constrained capacity of FTN signaling and only requires a low detection complexity. By deriving a new observation model suitable for FTN‐SCM, we offer the power allocation based on a

Pre-Equalized Interference Cancellation for Faster-Than-Nyquist Signaling
IEEE Access, 2019 An affine projection (AP)-based equalizer (APE) is introduced to eliminate the inter-symbol interference (ISI) for faster-than-Nyquist (FTN) signaling. Based on the APE, a pre-equalized interference cancellation (PIC) algorithm is proposed to eliminate ...

BER performance of finite in time optimal FTN signals for the Viterbi algorithm
Journal of Electronic Science and Technology, 2020 In this article, we consider the faster than Nyquist (FTN) technology in aspects of the application of the Viterbi algorithm (VA). Finite in time optimal FTN signals are used to provide a symbol rate higher than the “Nyquist barrier” without any encoding.
