Abstract: A signal is detected and an unwanted jamming signal is removed from the detected signal. Respective first, second and third correlations between a received signal and signals at first, second and third frequencies are determined over a plurality of taps. The second frequency is higher than the first frequency and lower than the third frequency, and is equally spaced from the first and third frequencies. The second frequency is adapted to a frequency of the received signal such that peaks in the first and third correlations after corresponding adaptation of the first and third frequencies have substantially equal magnitudes. A difference is determined between non-peak magnitudes of the first and third correlations; and at least one of the correlations is compensated for the effects of the jamming signal, based on said difference.
