Abstract: Systems and methods for reducing phase delay variation impact are described. A microcontroller can receive a sequence of phase offsets determined by a slave device over time. The microcontroller can determine a weight vector based on a metric associated with the sequence of phase offsets. The microcontroller can adjust a set of filter coefficients based on the weight vector. The set of filter coefficients can be filter coefficients of a filter being implemented by the slave device to filter incoming packet data.
