The disadvantages for meaning filter and Kalman filter are that real-time culling and modified singular value can not be removed and achieved in WIFI indoor position. This paper proposes an improved dynamic RSSI signal processing method. In order to improve the accuracy of dynamic RSSI signal processing, this algorithm is based on average hop distance and improved method of generalized least sq...

In recent years, active filters have been considered and developed for elimation of harmonics in power networks. Comparing with passive, they are smaller and have better compensating characteristics and resistance to line distortions. In this paper, a novel idea based on adaptive filter theory in presented to develop an active filter to eliminate the distortions of an arbitrary signal. Using th...

in this paper, an improved method (improved an-eul) is presented. this method is based on the combination of the analytical signal and the euler deconvolution method. two important parameters such as location and approximate geometry of a magnetic source can be obtained using the conventional an-eul method. altitude of ground and height in upward continuation has been considered for depth deter...

An approach for implementation of control system with anti-windup compensation using fault detection multifiltering is presented. The residual signal used for anti-windup compensation is obtained from a filter bank (i.e. multifiltering) for fault detection, thus it is not necessary its explicit measurement. This residual signal is considered as a fault, in order to design the fault detection fi...

Digital filters are widely used in signal processing and communication systems. In this achievement of the reliability of those systems is critical. So the fault tolerant filter implementations are needed. There are many techniques that exploit the filters’ structure and properties to achieve fault tolerance in order to reduce the complexity in the filter. In those complex systems, it is common...

Uniform suppression of fat signal is desired in clinical applications. Based on phase differences introduced by different chemical shift frequencies, Dixon method and its variations are used as alternatives of fat saturation methods, which are sensitive to B0 inhomogeneities. Iterative Decomposition of water and fat with Echo Asymmetry and Least squares estimation (IDEAL) separates water and fa...

In most practical adaptive signal processing systems, e.g., active noise control, vibration and acoustic echo cancellation, substantial nonlinearities that cannot be neglected exist. this paper, we analyze the behaviors of an system in which output filter has clipping saturation-type nonlinearity by a statistical-mechanical method. We discuss dynamical steady-state performing asymptotic analysi...

In many signal processing applications, adaptive frequency estimation and tracking of noisy narrowband signals is often required in communications, radar, sonar, controls, biomedical signal processing, and the applications such as detection of a noisy sinusoidal signal and cancellation of periodic signals. In order to achieve the objective of frequency tracking and estimation, an adaptive finit...

A novel wavelength-switchable single-longitudinal-mode (SLM) dual-wavelength erbium-doped fiber laser (EDFL) implemented based on a sigma architecture that is composed of a ring loop and a linear standing wave arm is experimentally demonstrated. Gain competition that prevents stable dual-wavelength oscillation is effectively suppressed by placing the gain medium in the standing-wave arm and by ...
