Abstract
A device includes a frequency offset (FO) compensation circuit coupled with a decoder, and a soft information measurement circuit. The frequency offset compensation circuit is configured to: (i) receive a continuous phase modulation (CPM) signal, (ii) adjust the CPM signal in a sampling window based on a frequency offset compensation value, and (iii) provide the adjusted CPM signal to the decoder. The decoder is configured to: (i) receive the adjusted CPM signal generated by the FO compensation circuit, (ii) decode the adjusted CPM signal to obtain one or more information symbols associated with the CPM signal, (iii) provide the one or more information symbols for soft information generation; and (iv) receive soft information provided by the soft information measurement circuit.
