DOI: 10.1109/tim.2017.2757158
Abstract: Double-threshold method is a typical and simple time-of-flight (TOF) measurement method for time-difference-based ultrasonic flowmeter. Some improvements have been proposed to suppress the cycle-skip phenomenon in double-threshold method. However, there are still some application limitations… read more here.

DOI: 10.1109/tvt.2025.3539645
Abstract: This study proposes a likelihood function (LF) learning method for time-varying multiple-input multiple-output (MIMO) systems using one-bit analog-to-digital converters. In time-varying channels, the initially-estimated LF becomes inconsistent with the true LF owing to channel variation.… read more here.
