In an aspect, an OWC transmitter transmits, to an OWC receiver, a first DC bias parameter, receives, from the OWC receiver, DC bias feedback based on a measurement associated with an OWC link between the OWC transmitter and the OWC receiver, and transmits an OWC signal with a second DC bias parameter that is based on the DC bias feedback from the OWC receiver. In another aspect, an OWC receiver receives, from an OWC transmitter, a first DC bias parameter, transmits DC bias feedback based on a measurement associated with an OWC link between the OWC transmitter and the OWC receiver, and receives, from the OWC transmitter, an OWC signal having a second DC bias parameter based on the DC bias feedback.
