Transmitter and receiver methods for improving asymmetrically-clipped optical OFDM

This paper introduces a new constellation mapping scheme for asymmetrically-clipped optical OFDM (ACO-OFDM) that puts more bits on the low-frequency subcarriers. The lowpass nature of the wireless optical channel motivates the use of this generic bit-loading scheme. This scheme has no knowledge of t...
