| titleOfInvention | Variable bandwidth filtering multi-tone modulation and demodulation method and system for satellite navigation communication |
| abstract | The invention discloses a method and system for variable bandwidth filtering multi-tone modulation and demodulation for satellite navigation communication. The variable bandwidth filtering multi-tone modulation method for satellite navigation communication comprises: subjecting a navigation signal and a communication signal to variable bandwidth filtering multi-tone modulation. modulate to obtain a modulated signal transmitted in a multi-subband channel; send the modulated signal; the variable bandwidth filtering multi-tone demodulation method for satellite navigation communication includes: receiving the modulated signal transmitted in the multi-subband channel; The modulated signal is jointly demodulated to obtain the communication signal and the navigation signal. The signal transmission scheme proposed by the present invention unifies the navigation channel and the communication channel through the specially designed variable-bandwidth filtering multi-tone modulation technology, and enables the navigation sub-channel and the communication sub-channel to coexist without changing the time-frequency domain structure. Thus, the spectrum utilization rate is improved, the signal rate of each carrier is reduced, and the cost and hardware complexity of each channel are reduced. |
