Smooth Approximation l 0-Norm Constrained Affine Projection Algorithm and Its Applications in Sparse Channel Estimation
We propose a smooth approximation l(0)-norm constrained affine projection algorithm (SL0-APA) to improve the convergence speed and the steady-state error of affine projection algorithm (APA) for sparse channel estimation. The proposed algorithm ensures improved performance in terms of the convergence speed and the steady-state error via the combination of a smooth approximation l(0)-norm (SL0) ...
متن کاملL0 Norm Based Affine Projection Sign Algorithm for Sparse Underwater Acoustic Channel Estimation under Symmetric Α-stable Noise
A new framework is proposed for deriving adaptive algorithms for sparse channel estimation under the presence of Symmetric α-Stable (SαS) noise. The algorithmic framework employs the natural gradient and incorporates both the Lp norm of the channel prediction error and the L0 norm of the complex-valued channel taps. Based on this framework, a novel affine projection sign algorithm is derived an...
متن کاملThe data-selective constrained affine-projection algorithm
This paper introduces a constrained version of the recently proposed set-membership affine projection algorithm based on the set-membershp criteria for coefficient update. The algorithm is suitable for linearly-constrained minimum-varianc filtering applications. The data selective property of the proposed algorithm greatly reduces the computational burden as compared with a nonselective approac...
متن کاملThe Constrained Affine Projection Algorithm — Development and Convergence Issues
This paper introduces the constrained version of the Affine Projection Algorithm. The new algorithm is suitable for linearly-constrained minimum-variance applications, which include beamforming and multiuser detection for communications systems. The paper also discusses important aspects of convergence and stability of constrained normalized adaptation algorithms in general. It is shown that no...
متن کاملBlock Sparse Memory Improved Proportionate Affine Projection Sign Algorithm
A block sparse memory improved proportionate affine projection sign algorithm (BS-MIP-APSA) is proposed for block sparse system identification under impulsive noise. The new BS-MIP-APSA not only inherits the performance improvement for block-sparse system identification, but also achieves robustness to impulsive noise and the efficiency of the memory improved proportionate affine projection sig...
