Abstract :
Optical wireless communication (OWC) systems employ simple low-cost intensity modulation and direct detection (IM/DD) techniques, which require that the electric signal must be real-valued and unipolar. Flip orthogonal frequency division multiplexing (Flip-OFDM) is one of the unipolar OFDM techniques developed for OWC. In this paper, we will analyze the clipping effects on Flip-OFDM and derive the achievable data rates under both average optical power and dynamic optical power constraints. Finally, the Flip-OFDM will be compared with the DC biased optical OFDM (DCO-OFDM).
