Spectrally efficient optical orthogonal frequency division multiplexing. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 This paper charts the development of spectrally efficient forms of optical orthogonal frequency division multiplexing (OFDM) that are suited for intensity-modulated direct detection systems, such as wireless optical communications. The journey begins with systems using a DC-bias to ensure that no parts of the signal that modulates the optical source ...
