    摘要： An optical orthogonal frequency division multiplexing (O-OFDM) system with pulse-width modulation (PWM) dimming includes a driver responsive to one or more predetermined dimming set points configured to generate PWM signals having a predetermined duty cycle and configured to supply current to one or more light emitting diodes (LEDs). An O-OFDM generator responsive to the one or more predetermined dimming set points and digital data is configured to generate digital inverted O-OFDM signals during on-states of the PWM signals and non-inverted O-OFDM signals during off-states of the PWM signals according to the predetermined duty cycle and convert the digital inverted O-OFDM signals and the digital non-inverted O-OFDM signals to analog output O-OFDM signals. A combiner circuit responsive to the current from the driver and the analog output O-OFDM signals is configured such that the analog output O-OFDM signals modulate the current to the one or more LEDs to provide a high capacity visible light communication link
