optical biasing in direct detection optical-OFDM for improving receiver sensitivity

FREE-DOWNLOAD A Ali, H Paul, J Leibrich… – National Fiber Optic …, 2010 –
Optical transmission systems employing orthogonal frequency division multiplexing (OFDM)
have gained considerable research interest because OFDM can combat fiber chromatic dispersion
[1,2] and has the capability to use higher level modulation formats to increase spectral .
