The proposed hybrid PLC/VLC network system utilises selective mapping (SLM) method for PAPR reduction and asymmetrically clipped optical-orthogonal frequency division multiplexing (ACO-OFDM).
However, AFDM has a crucial problem of high peak-to-average power ratio (PAPR), stemming from randomness of modulated symbols. To reduce the PAPR of AFDM, a novel algorithm named grouped pre-chirp ...
