A sparse block exact affine projection algorithm

IEEE Transactions on Speech and Audio Processing, 2002
The so-called affine projection algorithm (APA) has become a popular method in adaptive filtering applications and fast versions of it have been developed previously, such as fast affine projection (FAP) and the frequency domain block exact fast affine projection (BEFAP).

Complex proportionate-type affine projection algorithms

2013 Asilomar Conference on Signals, Systems and Computers, 2013
An extension of complex proportionate-type normalized least mean square algorithms is proposed and derived. This new algorithm called the complex proportionate-type affine projection algorithm helps the estimation of unknown impulse responses when the input signal is colored.

A Variable Regularization Method for Affine Projection Algorithm

IEEE Transactions on Circuits and Systems II: Express Briefs, 2010
The affine projection algorithm (APA) is a generalization of the normalized least mean square algorithm. We propose a variable regularization factor for the APA. Instead of the conventional assumption that the a posteriori error is zero, we incorporate the statistical characteristic of the noise into the adaptation process based on a system ...

A fast instrumental variable affine projection algorithm

Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002
We derive a new adaptive filtering algorithm called the instrumental variable affine projection (IVAP) algorithm and give its fast version (FIVAP algorithm). The IVAP algorithm departs from the AP algorithm and uses an IV. The IV process is generated in a way such that the new algorithm combines between the AP and the fast Newton transversal filter ...

Time-variant regularization in affine projection algorithms

2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013
We propose a time-variant regularization in affine projection algorithms, where we update the regularization parameter with a gradient method using a momentum term parametrized by a momentum rate. To further improve the convergence properties of the algorithm in transient stages while ensuring a small final misadjustment, we adaptively estimate the ...

Family of Affine Projection Algorithms

2015
After the birth of the basic affine projection algorithm (B-APA) in the middle of 1980s, several adaptive filtering algorithms that also exploit multiple regressors were put forward independently. They are now recognized as variants of the B-APA, forming a family of affine projection algorithms.

Kernel Affine Projection Algorithm

2015
The unknown system to be identified by an adaptive filter is usually assumed to be a linear system. Based on this assumption, we model the unknown system by a linear filter. In reality, however, there are cases where a linear filter is inadequate. In spite of this problem, using a very general nonlinear filter is not a good idea.
