The vision of researchers to create smart environments through the deployment of
thousands of sensors, each with a short range wireless communications channel and …

The microseismic signal is easily affected by observation noise and the inaccurate
estimation of traditional methods will seriously reduce the location accuracy of the …

Correlation coefficient is usually used to measure the correlation degree between two time
signals. However, its performance will drop or even fail if the signals are noised. Based on …

This paper presents an analysis of the time delay difference between the outputs of two
matched filter channels, in the presence of parametric mismatch. A theorem for computing …

Time delay estimation (TDE)-based algorithms for estimation of direction of arrival (DOA)
have been most popular for use with speech signals. This is due to their simplicity and low …

In this paper the problem of estimating the difference in arrival times of non-Gaussian
signals at two spatially separated sensors is considered. It is assumed that the signals were …

Most of the work presented in this chapter was done under two research projects: Semantic
Information Fusion and Reactive Sensor Networks. These projects were performed at the …

This paper presents various positioning algorithmsbased on Time Difference of Arrival
(TDOA) for impulsive type acoustic source localization inboth reverberant indoor and free …

1.1 Background Robots in the United States have been practically introduced into many
industries since the mid-20thcentury. There are industrial robots more than 1,000,000 units …

In this paper the problem of signal source localization is considered. The signals are
generated by footsteps and received by seismic sensors. This problem is encountered in …
