A Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms
In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...
متن کاملA Family of Variable Step-Size A ne Projection Adaptive Filtering Algorithms with Selective Regressors and Selective Partial Updates
This paper presents a family of Variable Step-Size (VSS) A ne Projection (AP) adaptive ltering algorithms with Selective Partial Updates (SPU) and Selective Regressors (SR). The presented algorithms have good convergence speed, low steady state Mean Square Error (MSE), and low computational complexity features. The stability bounds of the family of SPU-APA, SR-APA and SPU-SR-APA are analyzed, b...
متن کاملPartial-Update L∞-Norm Adaptive Filtering Algorithm with Sparse Updates
This paper provides a partial-update normalized sign least-mean square (NSLMS) algorithm with sparse updates. The proposed algorithm reduces the computational complexity compared with the conventional L∞-norm adaptive filtering algorithms by decreasing the frequency of updating the filter coefficients and updating only a part of the filter coefficients. And we develop a mean square analysis to ...

متن کاملAdaptive Filters Employing Partial Updates
{ In some adaptive ltering applications, the least-mean-square (LMS) algorithm may be too computationally-and memory-intensive to implement. In this paper , we analyze two adaptive algorithms that update only a portion of the coeecients of the adaptive lter per iteration. These algorithms use decimated versions of the error and regressor signals, respectively. Simulations verify the accuracy of...
