On time delay estimation using an FIR filter

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...

Statistical analysis of a watermarking system based on Bernoulli chaotic sequences

Real-time implementation of the moving FFT algorithm

An integrated algorithm for analyzing the real-time, running Fourier spectra is presented. When applying to the real-time analysis, the computational e$ciency and synchronization ability are highly improved by integrating the recursive procedure with the real-time implementation strategy. Given the FFT (frame) size N"2r and moving size M"2p, the algorithm implements the recursive procedure for ...

A contribution to (neuromorphic) blind deconvolution by flexible approximated Bayesian estimation

`Bussgang ' deconvolution techniques for blind digital channels equalization rely on a Bayesian estimator of the source sequence deened on the basis of channel/equalizer cascade model which involves the deenition of deconvolution noise. In this paper we consider four`Bussgang' blind deconvolution algorithms for uniformly-distributed source signals and investigate their numerical performances as...
