In this paper, we propose low complexity bit rate
variable transponders for adaptive DC biased Optical OFDM systems. The transponders are based on an alternative transform, the fast Hartley transform (FHT), and use adaptively modulated
O-OFDM (AMO-OFDM) to introduce flexibility to optical networks. Additionally, low complexity selective mapping (LC-SLM) technique is included in the bit rate variable transponders
to mitigate the effects of the peak-to-average power ratio (PAPR)and reduce the clipping noise, enabling the use of low bias values. |
