| 摘要 |
The invention relates to a method and device for generating a high frequency signal which is particularly suitable for the transmission of time and frequency information. The invention is characterized by a characteristic high-frequency spectrum represented above the axis in the Fig. A lower (3) and higher (4) sideband is symmetrical with the suppressed carrier (2), whereby the spectral bandwidth of said sidebands is low in comparison with the frequency distance (5). Both sidebands are modulated with a spread code in order to resolve ambiguity. The invention also relates to a receiver device which is particularly tolerant with respect to disturbing influences and used to evaluate the group delay time of the high frequency signal. |
