Digital modulation waveforms for use in ranging systems |
| 摘要 |
<p>A method of generating a subcarrier modulation signal adapted to modulate a ranging signal of a satellite positioning system. The method comprises a step of multiplexing in the time domain portions of a BOC (5,1) and a BOC (1,1) subcarriers to produce the subcarrier modulation signal. The time multiplex can be used to influence the location of the spectral peaks associated with the BOC subcarriers within the spectrum of the subcarrier modulation signal.</p> |
