PAPR reduction technique for FBMC based visible light communication systems
IET Communications, 2022 One of the critical challenges in multicarrier‐based systems is peak to average power ratio (PAPR). Recently, Filter Bank Multicarrier (FBMC) is proved to be a promising candidate that can replace the traditional orthogonal multiplexing division (OFDM ...

Proposed Combined PTS with Clipping and Filtering Technique for PAPR Reduction in OFDM System [PDF]
Engineering and Technology Journal, 2012 One of the major drawbacks of OFDM is high Peak-to-Average Power Ratio(PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier.
