Hexagonal Multicarrier Faster-Than-Nyquist Signaling
IEEE Access, 2017 Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient modulation scheme for future communication systems. In MFTN signaling, the intersymbol interference (ISI) and intercarrier interference (ICI) are introduced intentionally by the ...

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.Orthogonal frequency division multiplexing (OFDM) is a widely used modern communications technology due to its resistance to selective frequency fading and efficient use of spectrum. However, the security of OFDM signals remains a source of serious concern, especially in the face of network encryption that aims to disrupt communications or extract ...

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.In this paper, optical routers play an indispensable role in the ONoCs. The 4 × 4, 5 × 5, and scalable optical routers based on Mach–Zehnder interferometer (MZI) and microring resonator (MRR) are proposed. These routers are designed for a deadlock‐free Odd–Even turning model.

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.This research paper proposes three joint transmit and receive (TX/RX) beamforming schemes for minimizing the bit error rates of next‐generation wireless sensor networks. Based on minimizing the optimization problem of the total mean squared error between the transmitted and received data symbols, the first beamforming scheme is proposed.

Amplify-and-Forward in Wireless Relay Networks
, 2011 A general class of wireless relay networks with a single source-destination pair is considered. Intermediate nodes in the network employ an amplify-and-forward scheme to relay their input signals.

Intersymbol interference in duobinary systems
Electronics Letters, 1972 An upper bound for the error probability due to intersymbol interference and Gaussian noise is calculated for duobinary signalling systems. The duobinary system with twice the binary signalling speed has an error rate in excess of that of a binary system using identical filters.
