<p>A method, device and system for modulating complex carriers are provided in the invention. Wherein e -i?t or e i?t is used as a carrier frequency to perform carrier modulation for the signals to be carry. The modulated signals transmitted in the media are rotated complex signals. Using the method can enable right and left frequency bands to carry independent information. Therefore the spectrum utility ratio is improved. Employing the method for modulating the complex carriers provided in the invention can use the right and left spectrum resources adequately, and the loss of signal energy is small, therefore the capacity of the channel is improved greatly.</p> |
