Abstract
Disclosed are a signal processing method and a signal processing circuit for suppressing Co-Channel Interference (CCI). By using the signal processing method and the signal processing circuit provided by the instant disclosure, determining whether each subcarrier is affected by CCI will be more precise because the non-data subcarrier and the data subcarrier are both processed. Moreover, in the instant disclosure, the results to determine whether the subcarriers are affected by CCI are recorded as an N×K error matrix, and thus the receiver may detect the static interference and the dynamic interference according to this N×K error matrix.
