An Enhanced Non-Coherent Pre-Filter Design for Tracking Error Estimation in GNSS Receivers
Sensors, 2017 Tracking error estimation is of great importance in global navigation satellite system (GNSS) receivers. Any inaccurate estimation for tracking error will decrease the signal tracking ability of signal tracking loops and the accuracies of position fixing,

Adaptive finite-time parameter estimation for grid-connected converter with LCL filter
Frontiers in Energy Research, 2022 This study proposes an online finite-time adaptive parameter estimation method for grid-connected voltage source inverter (VSI) with LCL filter. In this framework, a time-continuous state-space system model is first developed, which is different from the

Reliable Eigenspace Error Estimation Using Source Error Estimators
Computational Methods in Applied MathematicsAbstract We introduce a framework for repurposing error estimators for source problems to compute an estimator for the gap between eigenspaces and their discretizations. Of interest are eigenspaces of finite clusters of eigenvalues of unbounded nonselfadjoint linear operators with compact resolvent.

Two New Families of Local Asymptotically Minimax Lower Bounds in Parameter Estimation
EntropyWe propose two families of asymptotically local minimax lower bounds on parameter estimation performance. The first family of bounds applies to any convex, symmetric loss function that depends solely on the difference between the estimate and the true ...
