In this paper, we propose a novel angle tracking algorithm, called as FPAT, for tracking multiple narrowband targets. The proposed algorithm modifies the algorithm presented by Park, et al. in two ways by using the sensor array output vector rather than the sample covariance matrix and by incorporating the extended Kalman filter instead of a simple Kalman(More)
Many direction-of-arrival (DOA) estimation algorithms for acoustic sources based on sensor array measurements have been well developed and verified via computer simulations and/or small-scale water trough experiments. However, these results are not in practical use because the testing scenarios may not reflect real underwater environments. In order to have(More)
Nonlinear effects arise in the high-density magnetic recording, which causes a performance degradation of the corresponding detector. Design of the timing recovery is crucial for the detector, and it becomes complicated in the presence of the nonlinear effects. In this article, we examine the effects of the Muller & Mueller's phase detector for a(More)
The realization of a digital phase-locked loop (DPLL) requires to choose a suitable phase detector and to design an appropriate loop filter; these tasks are commonly nontrivial in most applications. In this paper, the phase detector is examined, and a simple model is given to describe the characteristics of the timing function. The DPLL system is then(More)
