Teunissen, P.J.G. (author), Khodabandeh, A. (author)In this contribution, we generalize PPP–RTK theory by allowing the transmitters to transmit on different frequencies. The generalization is based on the integer-estimability theory of Teunissen (A new GLONASS FDMA model. GPS Solutions, 2019). As the theory and associated algorithms provided are generally applicable, they apply to satellite...journal article 2022

Kuo, Feng-Wei (author), Babaie, M. (author), Chen, Huan-Neng (Ron) (author), Cho, Lan-Chou (author), Jou, Chewn-Pu (author), Chen, Mark (author), Staszewski, R.B. (author)We propose a time-predictive architecture of an all-digital PLL (ADPLL) for cellular radios, which is optimized for advanced CMOS. It is based on a 1/8-length time-to-digital converter (TDC) of stabilized 7-ps resolution, as well as wide tuning range, and fine-resolution class-F digitally controlled oscillator (DCO) with only switchable metal...journal article 2018
