Abstract
A signal transmission and reception device and method are provided. The transmission method comprises generating multiple optical carriers from a basic optical carrier; modulating optical carriers, except for a predetermined optical carrier, in the optical carriers by using multiple data signals respectively, to generate multiple optical modulated signals; and synthesizing the multiple optical modulated signals and the predetermined optical carrier into a single optical signal, and transmitting the signal. The reception method comprises separating an optical signal into multiple optical carriers, the optical carriers having different frequencies and including a predetermined optical carrier; generating from the predetermined optical carrier multiple optical waves, frequencies of which correspond to frequencies of optical carriers, except for the predetermined optical carrier, in the multiple optical carriers; and demodulating the optical carriers, except for the predetermined optical carrier, in the multiple optical carriers by using the multiple optical waves respectively.
