We propose a multi-tap look-up-table(LUT)-based error-tracking decision feedback equalizer with partial unrolling(ET-DFEPU)algorithm to improve log-likelihood ratio(LLR)quality with error propagation.We introduce an e...

High peak-to-average power ratio(PAPR)is a major drawback of discrete multi-tone(DMT)in peak-power-constraint(PPC)intensity-modulation/direct-detection(IM/DD)optical systems.Symmetric clipping operation is a frequentl...
Optical Wireless Communication(OWC)is a new trend in communication systems to achieve large bandwidth,high bit rate,high security,fast deployment,and low cost.The basic idea of the OWC is to transmit data on unguided ...
