Patent ID: 8416839

Claim:
A method of receiving a radionavigation signal modulated by a modulation waveform, the modulation waveform comprising binary offset carrier (BOC) components, a BOC(n 1 ,m) component and a BOC(n 2 ,m) component, n 1 differing from n 2 , the method comprising: performing a correlation, over a time interval of duration T, between a prompt local waveform and said modulation waveform; and performing, over the time interval of duration T, a correlation between an offset local waveform and said modulation waveform, wherein said prompt local waveform is generated as a binary waveform comprising over said time interval at least one segment of a BOC(n 2 ,m) waveform of a total duration of (1−αA)T over said time interval, αA being a parameter greater than or equal to 0 and strictly less than 1, and said offset local waveform is generated as a binary waveform comprising over said time interval at least one segment of a BOC(n 1 ,m) waveform of a total duration of αBT over said time interval, αB being a parameter strictly greater than 0 and less than or equal to 1, and the parameters αA and αB being different.
