This paper presents a methodology to design a sparse multiband ranging signal with a large
virtual bandwidth, from which time delay and carrier phase are estimated by a low …

Time-based ranging accuracy is inversely proportional to the signal bandwidth. A larger the
signal bandwidth leads to a higher accuracy of time delay estimation, but more complex …

This paper explores the potential benefits of combining the use of injection-locking
techniques with GPS signals as a common clock source when applied to a low-cost …
