AB  - sIn visible light communication (VLC) systems, a non-orthogonal multiple access 
      (NOMA) scheme is deemed promising technology to offer better spectral efficiency 
      than the Orthogonal multiple access (OMA) scheme. The feasibility of power domain 
      NOMA for VLC system has been studied with different variants of unipolar OFDM 
      schemes. However, few research works have been presented on the impact of 
      clipping noise on the achievable sum rate of NOMA with DC-biased optical OFDM 
      (DCO-OFDM) and polarity divided DCO-OFDM (PD-DCO-OFDM). This paper presents the 
      impact of clipping noise on the achievable sum rate of NOMA-DCO-OFDM and 
      NOMA-PD-DCO-OFDM VLC systems. Moreover, NOMA-DCO-OFDM and NOMA-PD-DCO-OFDM 
      systems are compared based on achievable sum rates for different total power 
      constraints and signal clipping levels. For the two-user scenario, Simulation 
      results have confirmed that NOMA-PD-DCO-OFDM can offer a better sum rate compared 
      to NOMA-DCO-OFDM system.
