The focus of this paper is the estimation a delay between two signals. Such problem common in signal processing and particularly challenging when non-stationary nature. Our proposed solution based on an all-pass filter framework comprising elements: time equivalent to filtering can be represented terms ratio finite impulse response (FIR) its reversal. Using these elements, we propose adaptive a...

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...

This paper addresses the joint path delay and time-varying complex gain estimation for continuous phase modulation (CPM), over a time-selective slowly varying Rayleigh flat fading channel. We propose two estimation methods: an expectation-maximization (EM) algorithm for path delay estimation in a Kalman framework, and a Maximum a Posteriori (MAP) method for joint path delay and complex gain est...

In this paper, an observer design is proposed for linear time delay systems. An easy way to compute least square estimation error of an observer for time delay systems is derived, where the time delay terms exist in the state and output of the system. Based on the least square estimation error an optimization algorithm to compute a Kalman filter for time delay systems is proposed. By employing ...

Anticipation of predictable events is crucial for organizing motor performance. Using instructed delay tasks, it has been shown that even when delay duration is kept constant, reaction time fluctuates from trial to trial. As time estimation is at the core of anticipatory behavior, it is reasonable to speculate whether neuronal delay activity correlates with the subjective estimate of time. As a...

Abstract: Accurate channel estimation is necessary for coherent detection and adaptive control techniques, e.g., adaptive modulation and demodulation, of multicarrier signals. In this paper, we study one-dimensional channel estimation in frequencyor time-domain and 2-dimensional channel estimation in time-frequency domain. It is shown that the frequency (time)-domain interpolation channel estim...
