On time delay estimation using an FIR filter
نویسنده
چکیده
Abstract : A popular technique for time delay estimation is to use an FIR filter to model the time difference and the filter weights are interpolated with a sinc function to obtain the delay estimate. However, the sinc interpolator requires a sufficiently long filter length for accurate delay estimation. In this paper, we propose to process the filter weights via a least squares based method in order to acquire optimum delay estimates even with short filter lengths.

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

متن کاملTime Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter
In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...
متن کاملLimitations of Fir Multi-microphone Speech Dereverberation in the Low-delay Case
In this paper multi-microphone dereverberation is considered under the constraint that no or little additional delay should be introduced by the FIR deconvolution filters. This is crucial for a number of applications such as hearing aids etc. Assuming that the acoustic impulse responses (AIRs) are known – e.g. by estimation, we determine the maximum degree of attainable dereverberation. Even th...
