Radar Distance Measurement With Viterbi Algorithm to Resolve Phase Ambiguity
IEEE transactions on microwave theory and techniques, 2020In this article, a precise phase-based radar distance measurement system using a Viterbi decoder to resolve phase ambiguity is presented. Relying on the frequency-modulated continuous-wave radar principle, the introduced method evaluates both the ...

Featherlight Reuse-Distance Measurement
International Symposium on High-Performance Computer Architecture, 2019Data locality has a profound impact on program performance. Reuse distance—the number of distinct memory locations accessed between two consecutive accesses to the same location—is the de facto, machine-independent metric of data locality in a program ...

Precise Underwater Distance Measurement by Dual Acoustic Frequency Combs
Annals of Physics, 2019Underwater acoustics is of fundamental importance for marine science and technology. However, acoustic waves transmitted by state‐of‐the‐art underwater acoustic systems are not inherently phase locked, which hinders the development of underwater acoustic

Development and Validation of a Distance Measurement System in Metro Lines
IEEE transactions on intelligent transportation systems (Print), 2019While different location technologies have been used to collect data for trains, the development and validation of new systems remain a challenge. In this paper, a formal approach is presented for the development and verification of a new metro train-to ...
