TY - JOUR AU - Dzhezyan, Gregory AU - Kulhandjian, Michel AU - Kulhandjian, Hovannes PY - 2022 TI - Implementation of Faster-than-Nyquist Signaling using Software Defined Radios JF - Proceedings of the GNU Radio Conference; Vol 7 No 1 (2022): Proceedings of the 12th GNU Radio Conference KW - N2 - In this paper, we consider the development and implementation of a faster-than-Nyquist (FTN) signaling system using a binary phase-shift keying modulation (BPSK). We present a review of the theory and pertinent historical works related to the FTN signaling scheme, as well as practical work carried out in a laboratory environment. The popular open-source, and radio-specific, signal processing application GNU Radio was used to develop transmitter and receiver architectures. These architectures were then deployed for execution on various software-defined radio (SDR) hardware. We have evaluated the minimum Euclidean distance (MED) and probabilistic data association (PDA) estimators performance in terms of bit-error-rate (BER). We observed for higher noise variance to achieve a BER of 10^−3 with τ = 0.8 when using MED and τ = 0.9 when using PDA. UR - https://pubs.gnuradio.org/index.php/grcon/article/view/126
