Abstract:
1. A method of receiving a radionavigation signal, the method comprising: receiving the radionavigation signal modulated by a composite waveform with a receiver, the composite waveform comprising a linear combination with real-valued coefficients of a BOC(n performing a correlation between a local waveform and said composite waveform over a time interval of duration T with a correlation device, wherein the local waveform is a binary waveform, formed over said time interval by an alternating succession comprising at least one BOC(n 1 ,m) waveform segment and at least one BOC(n 2 ,m) waveform segment, the at least one BOC(n 1 ,m) segment having a total duration of αT, α being strictly between 0 and 1, the at least one BOC(n 2 ,m) segment having a total duration of (1−α)T.
