  • METHOD AND GENERATOR FOR GENERATING A SPREAD-SPECTRUM SIGNAL
    Publication number: 20100074302
    Abstract: A method of generating a spread-spectrum signal in a navigation system comprises the steps of providing a carrier wave and a modulation waveform and modulating the carrier wave with the modulation waveform. The modulation waveform comprises a so-called anti-phase linear combination of a BOC(1,1) waveform and a BOC(m,1) waveform, expressible as ?·BOC(1,1)??·BOC(m,1), where m represents an even integer number, ? and ? are non-zero coefficients of the same sign, indicating the relative power split between the BOC(1,1) waveform and the BOC(m,1) waveform.
