Parametric Convergence Analysis of an Adaptive Filtering Algorithm with Output Quantization

Sholeh Yasini and Torbjörn Wigren

June 2017

This report analyses global parametric convergence properties of a recursive algorithm for identification of linear finite impulse response (FIR) dynamics with quantized output measurements. The problem is addressed by analytic calculation of the right hand side of the associated ODE for a second order model. The ODE is then analysed numerically to investigate the possibilities for proving parametric convergence based on the coupling between the switch point and the dynamic gain.
