Abstract
A device includes a frequency offset (FO) estimation circuit and a frequency offset compensation circuit coupled with the frequency offset estimation circuit. The frequency offset compensation circuit is configured to (i) receive a continuous phase modulation (CPM) signal, (ii) receive, from the FO estimation circuit, an uncompensated frequency offset for a wth sampling window of the CPM signal, (iii) generate a frequency offset compensation value for a w+1st sampling window of the CPM signal based on the uncompensated frequency offset for the wth sampling window, (iv) adjust the CPM signal in the w+1st sampling window based on the frequency offset compensation value, and (v) provide the adjusted CPM signal to a filter.
