Mixed Norm Constrained Sparse APA Algorithm for Satellite and Network Echo Channel Estimation
IEEE Access, 2018 We propose an improved proportionate affine projection algorithm (PAPA), which is realized by integrating a hybrid-norm constraint into the affine projection algorithm (APA) to estimate the cluster sparse signals that are happened in satellite and ...

Order in Affine and Projective Geometry [PDF]
Canadian Mathematical Bulletin, 1963 In this note we give a characterisation of ordered skew fields by certain properties of the negative elements.Properties of negative elements of a skew field K are then interpreted as statements about "betweenness" in any affine geometry over K, or as statements about "separation ...

Subband Affine Projection Algorithm for Acoustic Echo Cancellation System
EURASIP Journal on Advances in Signal Processing, 2007 We present a new subband affine projection (SAP) algorithm for the adaptive acoustic echo cancellation with long echo path delay. Generally, the acoustic echo canceller suffers from the long echo path and large computational complexity.

Sparse Adaptive Channel Estimation Based on lp-Norm-Penalized Affine Projection Algorithm
International Journal of Antennas and Propagation, 2014 We propose an lp-norm-penalized affine projection algorithm (LP-APA) for broadband multipath adaptive channel estimations. The proposed LP-APA is realized by incorporating an lp-norm into the cost function of the conventional affine projection algorithm (

Measurement Science Review, 2020 An active-vision process is presented by the affine invariability of the ratio of triangle areas to reconstruct the 3D object. Firstly, a plate with the triangle array is designed in the same plane of the planar laser. The image of the plate is rectified

Improving Performance of Affine Projection–Like Algorithm Using Two Combination Methods
Journal of Applied MathematicsThe affine projection–like (APL) algorithm has garnered significant attention due to its low steady-state mean-square deviation and simplicity. However, its performance is limited by a fixed step-size, which forces a trade-off between fast convergence ...

Low Cost Variable Step-Size LMS With Maximum Similarity to the Affine Projection Algorithm
IEEE Open Journal of Signal ProcessingThe LMS algorithm is widely employed in adaptive systems due to its robustness, simplicity, and reasonable performance. However, it is well known that this algorithm suffers from a slow convergence speed when dealing with colored reference signals ...
