Abstract
This paper presents relations for predicting the mean squared values in the deviations of the outputs in the conventional QRD-RLS algorithm due to quantization effects. A set of formulas are presented, along with a procedure to employ them to calculate the expected value of the squared norm of the tap deviation and the mean squared value of the error signal deviation. Simulation results are presented to show the accuracy of the obtained results
