Numerous works are dedicated to Faster-than-Nyquist (FTN) signaling providing symbol rate
higher than “Nyquist limit” without energy losses. It is necessary to use infinite pulses or …

This paper proposes new formulation and solution of optimization problems to synthesis
bandwidth-efficient signals. Different types of optimization problems such as maximizing free …

Optimal signals represent the branch of FTN signaling and may be used for spectral
efficiency improvement. Such signals may be detected with a simple coherent bit-by-bit …

In this paper, we investigate the performance of massive MIMO systems in a single cell using
independent and identically distributed (iid) Rayleigh channels. This includes studying the …

In communication systems, in order to increase spectrum efficiency, pulses with limited
bandwidth that meet the Nyquist zero intersymbol interference criterion are usually used for …

Для развития будущих поколений сетей связи требуется повышать как спектральную,
так и энергетическую эффективность. Первого можно добиться за счет применения …

To develop future generations of networks it is necessary to improve both spectral and
energy efficiency. The first one may be improved due to the application of optimal faster than …

This paper studies various sub-optimal versions of BCJR demodulator to examine the
possibility of computational reduction. BCJR demodulator is used to deal with intentional …
