Anti-forwarding-interference direct sequence spread spectrum receiver and anti-forwarding-interference method

The invention discloses an anti-forwarding-interference direct sequence spread spectrum receiver and an anti-forwarding-interference method, and belongs to the field of communication. The method comprises the following steps: firstly, calculating correlation value power after matched filtering of a spreading code; searching for several maximum power values in a spreading code period, grouping thepower values, judging whether forwarding interference exists or not by combining grouping, the power values and interval delay of two maximum groups, and switching frequency points by utilizing an alarm mechanism of a console, thereby achieving the purpose of resisting forwarding interference. The method provided by the invention has the characteristics of simple and effective algorithm implementation, no need of adding extra anti-forwarding interference overhead to a channel link and no need of adding an anti-forwarding interference function to other equipment in a receiving system, and is particularly suitable for a
