Receiving and transmitting radio frequency signals
First Claim
1. A method of receiving and transmitting radio frequency signals by a vehicle (8), the method comprising:
- providing a transceiver module (28), the transceiver module (28) being located onboard the vehicle (8), the transceiver module (28) comprising a plurality of transceivers (40-56), each transceiver (40-56) being configured to operate within a different respective radio frequency band;
providing a waveform library (30) containing a plurality of different waveform specifications (80), the waveform library (30) being located onboard the vehicle (8),receiving, by a first transceiver of the transceiver module (28), a first radio frequency signal having a first frequency and a first waveform, the first frequency being a frequency within a first radio frequency band, the first radio frequency band being a band within which the first transceiver is configured to operate;
determining, using the first frequency, by a communications management module (36) located onboard the vehicle (8) and operatively coupled to the transceiver module (28), a second frequency, the second frequency being different to the first frequency and being within a second radio frequency band that is different to the first radio frequency band;
selecting, using the first waveform, by the communications management module (36), a second waveform corresponding to one of the plurality of waveform specifications (80) stored in the waveform library (30), the second waveform being different to the first waveform;
acquiring, by a waveform synthesiser, from the waveform library (30), a waveform specification (80) for the second waveform;
synthesising, by the waveform synthesiser (66), using the acquired waveform specification (80) for the second waveform, a signal having the second frequency and the second waveform; and
transmitting, by a second transceiver of the transceiver module (28) configured to operate within the second radio frequency band, the synthesised signal;
wherein the second frequency and the second waveform are chosen so as to minimize receiver desensitization.
