摘要:
In accordance with an example embodiment of the present invention, a method is disclosed that comprises by using a processor, calculating a plurality of signal states for each of at least two carriers, selecting at least one carrier from the at least two carriers, generating modified signal states for each of the selected at least one carrier by rotating at least one of the respective plurality of signal states with a discrete frequency shift step, determining combinations of signal states of the at least two carriers based at least in part on the modified signal states of the selected at least one carrier, and calculating a cubic metric based on the determined combinations of signal states of the at least two carriers.
