Abstract
A method for detecting multi-path interference in a spread-spectrum signal. A variation of a first signal and a variation of a second signal is compared. The variation of the first signal corresponds to a correlation of the spread-spectrum signal and a spreading code having a first offset. The variation of the second signal corresponds to a correlation of the spread-spectrum signal and the spreading code having a second offset. Multi-path interference is detected in dependence on the comparison.
