Fast subsampled-updating stabilized fast transversal filter (FSU SFTF) RLS algorithm for adaptive filtering
We present a new, doubly fast algorithm for Recursive Least-Squares (RLS) adaptive ltering that uses displacement structure and subsampled-updating. The Fast Subsampled-Updating Stabilized Fast Transversal Filter (FSU SFTF) algorithm is mathematically equivalent to the classical Fast Transversal Filter (FTF) algorithm. The FTF algorithm exploits the shift invariance that is present in the RLS a...
متن کاملThe Fast Subsampled-Updating Fast Transversal Filter (FSU FTF) RLS Algorithmy
We present a new fast algorithm for Recursive Least-Squares (RLS) adaptive ltering that uses displacement structure and subsampled updating. The FSU FTF algorithm is based on the Fast Transversal Filter (FTF) algorithm, which exploits the shift invariance that is present in the RLS adaptation of a FIR lter. The FTF algorithm is in essence the application of a rotation matrix to a set of lters a...
متن کاملFast Transversal Recursive least-squares (FT-RLS) Algorithm
In this paper a brief overview of the Fast Transversal Recursive Least-Squares (FT-RLS) algorithm is provided. This algorithm is designed to provide similar performance to the standard RLS algorithm while reducing the computation order. This is accomplished by a combination of four transversal filters used in unison. Finite precision effects are also briefly discussed. Simulations are performed...
متن کاملOnline wavelet-based density estimation for non-stationary streaming data
There has been an important emergence of applications in which data arrives in an online time-varying fashion (e.g. computer network traffic, sensor data, web searches, ATM transactions) and it is not feasible to exchange or to store all the arriving data in traditional database systems to operate on it. For this kind of applications, as it is for traditional static database schemes, density es...
متن کاملAn Rls Based Adaptive Transversal Filter for Gps Narrowband Interference Cancellation
GPS signals are susceptible to interference levels above the inherent processing gain of the receiver. In this paper an innovative approach to cancel narrowband interference is presented. An Adaptive Temporal Filter (ATF) based on a Transversal form that pre-filters the interference before correlation is studied. The adaptive algorithm used to adjust the filter coefficients is the RLS algorithm...
