To receive a radio navigation signal modulated by a composite wave form, the composite wave form comprising a linear combination with real coefficients of a component BOC(n1,m) and of a component BOC(n2,m), n1 being different from n2, a correlation between a local wave form and the composite wave form over a time interval of duration T is carried out. The local wave form is a binary wave form, formed over said time interval of an alternating succession comprising at least one segment of wave form BOC(n1,m) and at least one segment of wave form BOC(n2,m), the at least one segment BOC(n1,m) having a total duration of αT, α being strictly between 0 and 1, the at least one segment BOC(n2,m) having a total duration (1−α)T.
A method of receiving a radionavigation signal modulated by a composite waveform, the composite waveform comprising a linear combination with real-valued coefficients of a BOC(n1,m) component and a BOC(n2,m) component, n1 differing from n2;
A receiver capable of receiving a radionavigation signal modulated by a composite waveform, the composite waveform comprising a linear combination with real-valued coefficients of a BOC(n1,m) component and a BOC(n2,m) component, n1 differing from n2,
