Method for treating signal in the presence of interference
First Claim
1. A method of signal processing in the presence of interference, this signal including a first wideband channel (WB) and a second narrowband channel (NB) modulating one and the same carrier (FO), comprising the step of simultaneously processing said two channels using a single phase loop and a single code loop.

Abstract
The invention relates to methods of processing signals subjected to interference. It consists, when this signal is formed of a first wideband channel and of a second narrowband channel modulating one and the same carrier in which these signals are cut off for the duration of the interference, in using a single phase loop and a single code loop to process these two channels simultaneously. It makes it easier to process signals in satellite based navigation systems of the GPS type when they are scrambled by the DME-type distance measuring system signals, as well as more generally making it possible to increase the robustness of the processing by joint processing of the bands broadcast to the users.
