1. A computer-implemented method, comprising:
identifying, using at least one processor, one or more symbol separations between one or more symbols in a plurality of symbols across one or more antennas receiving a signal including a frame having the plurality of symbols on a communication channel, the plurality of symbols including one or more symbol groups;
determining, using the at least one processor, one or more correlation metrics for at least one symbol group in the one or more symbol groups using the identified one or more symbol separations; and
generating, using the at least one processor, based on the determined one or more correlation metrics, one or more carrier frequency offsets associated with the signal received by the one or more antennas.
