This paper is connected with the development and application of special algorithm of digital signal processing for passive acoustic location using cheap equipment. The calculation of ambiguity function by spectral method is suggested instead of classical integration. The effectiveness of location is proved by full-scale experiments.
Joint analysis of complex signals is essential for a better understanding of the principles underlying the complex systems dynamics. In our work we studied the mutual dynamics of two Gaussian distributed stochastic processes exhibiting either short-term or long-term correlations. We generated two copies of each surrogate process and applied the amplitude randomization procedure to one of them. We...
This paper introduces a time-hopping (TH) system for rapid on-off-division duplex (RODD), with this method, virtual full-duplex communication at the frame transmission level can be realized. However because of the randomness of the transmission timing, the slots may have a collision with a high probability. So it's very important to establish a model to calculate the collision ratio, and analyze the...
In complex systems significant information about their inherent dynamics is hidden in the interactions between the system components and thus the analysis of the mutual information is essential for providing a better understanding of the principles underlying the system behavior. We focused on four different methods to assess the mutual information such as phase synchronization analysis; time delay...
With the development of mobile communication, adaptive algorithms are often chosen in real time process because of their high speed. However, existing adaptive algorithms are not suitable in frequency selective fading channels. In this paper, an improved adaptive synchronization algorithm is proposed for the application under frequency selective fading channels. A novel correlation function is proposed...
