GNSS Software-Defined Radio: History, Current Developments, and Standardization Efforts

“…The scope of SDRs was first extended to non-GNSS signals by McEllroy et al (2006). SDRs became the implementation of choice in numerous studies aimed at exploiting SOPs for navigation purposes (Diouf et al, 2021(Diouf et al, , 2019Kassas et al, 2017), such as (i) cellular 3G CDMA Pesyna et al, 2011;Yang & Soloviev, 2018), 4G LTE (del Peral-Rosado et al, 2017Ikhtiari, 2019;Kang et al, 2019;Wang et al, 2022;Yang et al, 2022), and 5G NR del Peral-Rosado et al, 2022;Fokin & Volgushev, 2022;Lapin et al, 2022;Santana et al, 2021;Shamaei & Kassas, 2021b;Tang & Peng, 2022); (ii) AM/FM radio (Chen et al, 2020;McEllroy, 2006;Psiaki & Slosman, 2022;Souli et al, 2021); (iii) digital television (Souli et al, 2020(Souli et al, , 2022Yang & Soloviev, 2020); and (iv) LEO satellites (Farhangian et al, 2021;Farhangian & Landry, 2020;Nardin et al, 2021;Orabi et al, 2021;Pinell, 2021;Zhao et al, 2022).…”
