In this paper we propose the technique for SEFDM modification assuming that the
conventional SEFDM is a particular type of partial response signals obtained from OFDM by …

In the paper, we compared spectral efficiency between OFDM signals, reputed SEFDM
signals, and recently proposed RRC-SEFDM and PR-SEFDM signals. The last three are …

Faster-than-Nyquist (FTN) signaling is the promising idea that theoretically provides a
significant increase in the spectral efficiency without energy loss. The gain is achieved …

In this paper we propose a utilization of infinite RRC-pulses (with finite root raised cosine
spectrum) as shapes for subcarriers' spectrums in spectrally efficient frequency division …

This paper proposes novel coded modulation schemes based on LDPC codes and optimal
partial response (or Faster-than-Nyquist) signals. In these schemes coded bits are mapped …

The approach to the selection of the amplitude limitation mode for decreasing the peak-to-
average power ratio (PAPR) of the Faster-Than-Nyquist (FTN) signals is presented. This …

An opportunity of finite-length optimal signals application to excess Nyquist limit without
energy losses and within defined occupied bandwidth is considered in this article. Finite …

The use of Kahn method or envelope tracking transmitters in communication systems will
increase their efficiency. However, the modulation power supply used in these transmitters …

This paper is devoted to detection of signals with intentionally introduced intersymbol
interference (ISI). Faster-than-Nyquist (FTN) signaling and optimal partial response …

The paper is devoted to the study of signals obtained as a solution of the optimization task.
This approach can be used in Faster-Than-Nyquist (FTN) signaling to provide extremely …
