In this paper, a decision tree algorithm based on time-domain digital technique is developed for the identification and classification of diverse radar intra-pulse modulated signals for the electronic intelligence system in real-time. This includes linear... see more

Pitch period evaluation of speech signal is used in many important applications of speech technology. However, among the existingmethods only some can work in case of non-linear and non-stationary signals. The main reason is that the pitch detection metho... see more

This paper presents a Flood Frequency Analysis (FFA), which takes into account the notion of characteristic duration. Instantaneous flood discharge data from Foum El Gherza station is used to develop flood-duration-frequency (QDF) curve, using the so-call... see more

The new methods of acceleration harmonic signal frequency tracking based on estimates ofinstantaneous frequency and phase, are proposed and investigated. Better efficiency of new systems e.g. quicker transient process and bigger frequency range is proved ... see more

Common sound source localization algorithms focus on localizing all the active sources in the environment. While the source identities are generally unknown, retrieving the location of a speaker of interest requires extra effort. This paper addresses the ... see more

A nonparametric computationally efficient algorithm is proposed for micro-Doppler frequency estimation, assuming that this non-linear micro-Doppler frequency is approximate linear frequency in short-time intervals. In this algorithm, we use Radon-Wigner t... see more

The estimation of instantaneous frequency (IF) method is introduced to compensate for the group velocity of electromagnetic wave in dispersive medium. The location of the reflected signal can be obtained by using the time-frequency cross correlation (TFCC... see more

Probe-based data collection system, which deploys movable sensors in traffic streams to collect traffic records, is commonly used for area-wide measurement of travel times and conditions of traffics on road networks. However, due to sparse distribution of... see more
