Embodiment Construction
[0024] The technical scheme of the present invention is described further below:
[0025] A fast signal processing method of an optical orthogonal frequency division multiplexing OOFDM transceiver includes signal sending and receiving. Described signal transmission carries out following processing: signal string / parallel conversion, the high-speed data of one road serial is converted into the low-speed data of multi-channel parallel;
[0026] Channel automatic detection and pseudo-code addition, according to the predetermined modulation mode, the multi-channel parallel low-speed data are respectively modulated and mapped, and the multi-channel information sequence is correspondingly obtained and expanded into a multi-channel information sequence with a Hermitian symmetric structure;
[0027] Inverse Fourier transform, performing fast inverse Fourier transform on the multi-channel information sequence with Hermitian symmetric structure and performing parallel / serial conversion ...
