PAPR reduction of optical OFDM signals in visible light communications
Orthogonal frequency division multiplexing (OFDM) is extensively used in optical communications to achieve high rate transmission. In this paper, Vandermonde like matrix (VLM) pre-coding approach is offered to reduce the high peak-to-average power ratio (PAPR) of DC-biased optical OFDM (DCO-OFDM) an...
