Abstract
A frequency manipulator comprises a frequency transformer and a frequency retransformer. The frequency transformer receives each of at least one signal in a known band from at least one transmitter, transforms the known band of each signal into a predetermined band and forwards each signal in the predetermined band to a channel device. The frequency retransformer receives each signal from the channel device, retransforms the predetermined band of each signal to the known band and forwards each signal in the known band to at least one receiver.
Claims14
A communication method, the method comprising:
- transforming more than one signal frequency of a plurality of signal frequencies in a known band to different signal frequencies in a predetermined band of a channel device different from the known band between transmission and reception such that frequency separation between the more than one signal frequency in the known band is different from frequency separation between the different signal frequencies in the predetermined band, the known band being different from the predetermined band;
- feeding the plurality of signal frequencies in the predetermined band through the channel device;
- and
- retransforming, after the channel device;
- the more than one signal frequency in the predetermined band to the known band for reception.
