Blind Adaptive Equalization in Additive Impulsive Noise Using the Logarithmic Product Fractional-Moment (LP-FM) Criterion
Shafayat Abrar
The blind mitigation of inter-symbol interference in additive white impulsive noise modeled by a symmetric -stable (SS) distribution is investigated. A novel logarithmic prod…
Design and Analysis of a Higher-Order Enhanced Phase-Locked Loop via the Ahmadi-Chaudhry-Zhang Newton Framework
Shafayat Abrar
The enhanced phase-locked loop (EPLL) is widely used in power systems to estimate the amplitude, phase, and frequency of sinusoidal voltages. Existing EPLL formulations are primari…
Steepest Descent Multimodulus Algorithm for Blind Signal Retrieval in QAM Systems
Shafayat Abrar
We present steepest descent (SD) implementation of multimodulus algorithm (MMA2-2) for blind signal retrieval in digital communication systems. In comparison to stochastic approxim…
Adaptive Blind Sparse-Channel Equalization
Shafayat Abrar
In this article, a fractional-norm constrained blind adaptive algorithm is presented for sparse channel equalization. In essence, the algorithm improves on the minimization of the…
Higher-Degree Stochastic Integration Filtering
Syed Safwan Khalid, Naveed Ur Rehman, Shafayat Abrar
We obtain a class of higher-degree stochastic integration filters (SIF) for nonlinear filtering applications. SIF are based on stochastic spherical-radial integration rules that ac…
