Abstract:
1. A method, comprising: receiving a radio frequency signal containing a multi-path component and converting said radio frequency signal to a digital signal; and detecting said multi-path component and determining using at least two pairs of correlation signals, each pair being symmetrical relative to a prompt point, whether a distortion of said radio frequency signal caused by said multi-path component meets a predetermined condition using a correlation analysis of said digital signal with said at least two pairs of the correlation signals by maintaining equal the correlation signals of one pair of said two pairs and evaluating a difference between the correlation signals of another pair of said two pairs, for implementing a multi-path detection analysis of said radio frequency signal by said spread spectrum receiver which is configured to make a decision whether to further process the received radio frequency signal using results of said multi-path detection analysis.
