Abstract
Disclosed is a method for receiving a radionavigation signal modulated by a composite waveform, the composite waveform comprising a linear combination with real-valued coefficients of a BOC(n,m) component and a BOC(n,m) component, ndiffering from n; in which a correlation is performed between a local waveform and the composite waveform over a time interval of duration T, wherein the local waveform is a binary waveform, formed over the time interval by an alternating succession comprising at least one BOC(n,m) waveform segment and at least one BOC(n,m) waveform segment, the at least one BOC(n,m) segment having a total duration of αT, α being strictly betweenand, the at least one BOC(n,m) segment having a total duration of (−α)T.
