<p>A complex carrier demodulation method and device are provided by the present invention. The complex signal is adopted, the modulated signal is demodulated using the e-i?t or ei?tas the carrier signal, and the complex carrier demodulation signal is obtained. Therefore, the utilization rate of the frequency spectrum is improved. With the complex carrier demodulation method provided by the present invention, the left and right frequency spectrum resources are utilized sufficiently, the loss of the signal energy is small, and therefore the capability of the channel is improved greatly.</p> |
