abstract = " We present a new modulation scheme for asymmetrically-clipped optical OFDM (ACO-OFDM). We show that a generic bit-loading scheme that puts more bits on the low-frequency subcarriers is more efficient for wireless optical channels than the constant modulation scheme typically used in radio frequency (RF) OFDM schemes. We discuss the lowpass nature of the wireless optical channel that motivates the use of this generic bit-loading scheme. This scheme performs significantly better than the traditional constant modulation on all tones in a variety of channels. The average Bit-error rate (BER) curves for the new modulation scheme have up to a 5 dB improvement for Signal-to-Noise Ratios where the BER is in the order of 10 -3 .",
