Method of reception and receiver for a radio navigation signal modulated by a CBOC or TMBOC spread waveform

Abstract : To receive a radio navigation signal modulated by a modulation waveform, the modulation waveform comprising a component BOC(n1,m) and a component BOC(n2,m), n2 being strictly less than n1, a correlation is performed between a prompt local waveform and the modulation waveform and a correlation is performed between a shifted (forward or backward) local waveform and said modulation waveform, over a time interval of duration T. The prompt local waveform is generated in the guise of a binary waveform comprising over said time interval at least one waveform segment BOC(n2,m) of a total duration of (1-[alpha]A)T over said time interval, [alpha]A being a parameter greater than or equal to 0 and strictly less than 1.; The shifted local waveform is generated in the guise of a binary waveform comprising over said time interval at least one waveform segment BOC(n1,m) of a total duration of [alpha]BT over said time interval, B being a parameter strictly greater than 0 and less than or equal to 1, and [alpha]A being different from [alpha]B.
