This letter presents a novel improved delay estimation methodology during scheduling in high level synthesis (HLS) for application specific computing. In general during delay estimation from scheduling during HLS, only functional unit delay is considered. However for current generation of complex digital systems, interconnects (switching elements) also play a very vital role in effective delay ...

Estimation of time delay between signals received at two spatially separated sensors has considerable practical importance in the applications like source localization, direction finding etc., in RADAR, SONAR and other communication systems. In this paper cross correlation (CC) generalized cross correlation with phase transform (GCCPHAT) and maximum likelihood (ML) estimation methods are used a...

Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...

delay is one of the principal measures of performance used to determine the level of service (los) at signalized intersections and several methods have been widely used to estimate vehicular delay. very few studies only have been carried out to estimate delay at signalized intersections under mixed traffic conditions prevailing in developing countries like india. in the present study, various p...

A channel delay can be estimated by evaluating the channel response to a deterministic signal. In the frequency domain, a maximum likelihood delay estimator which accounts for colored Gaussian measurement noise can be formulated. A procedure that allows fast estimation of the channel delay is proposed, in case a low-pass deterministic signal is applied to the channel. Keywords—Fractional delay;...

In this Letter, the problem of estimating the timedifference-of-arrival between signals received at two spatially separated sensors is addressed. By taking discrete Fourier transform of the sensor outputs, time delay estimation corresponds to finding the frequency of a noisy sinusoid with time-varying amplitude. The generalized weighted linear predictor is utilized to estimate the time delay an...
