A general estimation model is defined in which two observations are available; one being a noisy version of the transmitted signal, while the other is a noisy-filtered and delayed version of the same transmitted signal. The delay and the filter are unknown quantities that must be estimated. An adaptive system, based on the least squares (LS) estimation criterion, is proposed in order to perform...

This paper addresses the estimation of time delay between two spatially separated noisy signals by system identification modeling with the input and output corrupted by additive white Gaussian noise. The proposed method is based on a modified adaptive Butler-Cantoni equalizer that decouples noise variance estimation from channel estimation. The bias in time delay estimates that is induced by in...

This study describes a real time delay estimation method using probe data with adaptive signal control algorithm, “CARREN” (Control Algorithm Retuning paRameters with self performance EvaluatioN) [1]. So far, CARREN supposed the use of AVI (Automatic Vehicle Identifier) data to estimate the total delay on approaching each intersection. In this paper, the application of CARREN using probe data i...
