Abstract:
1. A spread spectrum receiver, comprising: a receiving block, configured to perform a correlation analysis of a digital signal generated from a radio frequency signal comprising a multi-path component using at least two pairs of correlation signals, each pair being symmetrical relative to a prompt point, 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; and a receiver processing block, configured to detect said multi-path component and determining whether a distortion of said radio frequency signal caused by said multi-path component meets a predetermined condition using said correlation analysis of said digital signal, and for making a decision whether to further process the received radio frequency signal using results of said multi-path detection analysis for implementing a multi-path detection analysis of said radio frequency signal by said spread spectrum receiver.
