Sliding Window Generalized Kernel Affine Projection Algorithm Using Projection Mappings
EURASIP Journal on Advances in Signal Processing, 2008 Very recently, a solution to the kernel-based online classification problem has been given by the adaptive projected subgradient method (APSM). The developed algorithm can be considered as a generalization of a kernel affine projection algorithm (APA ...

ZA-APA with Adaptive Zero Attractor Controller for Variable Sparsity Environment [PDF]
International Journal of Electronics and Telecommunications, 2020 The zero attraction affine projection algorithm (ZA-APA) achieves better performance in terms of convergence rate and steady state error than standard APA when the system is sparse. It uses l1 norm penalty to exploit sparsity of the channel.

A Blind Demodulation Algorithm for Underwater Acoustic MPSK Signal
IEEE Access, 2021 Multiple phase-shift keying (MPSK) is a common carrier modulation in underwater acoustic (UWA) communication. This paper proposes a robust blind demodulation algorithm to improve the performance and practicability of blind demodulation of MPSK signals ...

Geometric-algebra affine projection adaptive filter
EURASIP Journal on Advances in Signal Processing, 2021 Geometric algebra (GA) is an efficient tool to deal with hypercomplex processes due to its special data structure. In this article, we introduce the affine projection algorithm (APA) in the GA domain to provide fast convergence against hypercomplex ...

New proportionate affine projection sign algorithms [PDF]
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013 In this paper, two proportionate affine projection sign algorithms are introduced. The performance of the proposed algorithms is compared with that of other proportionate affine algorithms under impulsive interference environment of a network echo cancellation system. It is shown that one of the proposed algorithms, termed memory improved proportionate

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 ...
