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 $α$-stable (S$α$S) distribution is investigated. A novel logarithmic product fractional-moment statistics (LP-FMS) criterion is proposed by combining complementary fractiona…

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 primarily derived from first- or second-order optimization methods, which may exhibit slow convergence, sad…

Analyzing Uncertainty in the Spatial Representation of the Kinematic Bicycle Model

Shafayat Abrar, M. Zaeem Baig, Shahir Ul Islam Anzal, Abdul Basit Memon

Locating a vehicle and determining its orientation in an uncertain environment is a critical challenge in autonomous vehicle navigation and path planning. To address these challenges, a vehicle estimates its pose while depending on sensor data that offer noisy measurements. These…
