METHOD FOR TREATING A SIGNAL IN THE PRESENCE OF INTERFERENCE

摘要

The invention relates to methods for treating signals which are subjected to interference. According to the inventive method, when a signal is formed from a first wide band channel (WB) and a second narrow band channel (NB) modulating the same carrier (FO), wherein said signals are cut off during the duration of the interference (DME), a single phase loop (220,221,201-207) and a single code loop (222,223,208-218) are used to treat two channels simultaneously. The treatment of signals in GP-type satellite navigation systems is thus facilitated when they are subjected to interference by DME-type distance measurement signals, more generally the robustness of the treatment is increased by joint treatment of the bands which are broadcast to users.
