Abstract
An interference processing method comprises: receiving a multi-carrier modulated signal, wherein the multi-carrier modulated signal comprises multi-carrier modulation symbols; discomposing the multi-carrier modulation symbols into a set of subcarriers, wherein the set of subcarriers at least comprises a target subcarrier; equalizing the target subcarrier to obtain an equalized target subcarrier; obtaining an error power of the equalized target subcarrier; and comparing the error power of the equalized target subcarrier with a predefined threshold to determine the existence of interference in the target subcarrier, wherein the predefined threshold is associated with a minimum distance between two constellation points of a modulation constellation of the target subcarrier.
