METHOD AND DEVICE FOR GENERATING AND RECEIVING OOFDM SIGNAL, AND WAVELENGTH-DIVISION MULTIPLEXING SYSTEM |
摘要 |
Embodiments of the present invention relate to the field of communications, and in particular, disclose a method and a device for generating and receiving an OOFDM signal, and a wavelength-division multiplexing system. The method for generating an OOFDM signal includes: converting a channel of serial high-speed data to N channels of parallel low-speed data; performing modulation mapping on the N channels of parallel low-speed data respectively to obtain N channels of information sequences; expanding the N channels of information sequences to 2N+2 channels of information sequences which have a Hermitian symmetric structure; performing inverse Fast Fourier Transform on the 2N+2 channels of information sequences, and then performing parallel-to-serial conversion to obtain an OFDM baseband signal; performing digital-to-analog conversion on the OFDM baseband signal to obtain an OFDM analog signal; and modulating the OFDM analog signal to an optical carrier to obtain an OOFDM signal.
