Abstract: Described herein are techniques for self-synchronization of wireless nodes. For example, the technique may involve determining a repetition rate for receiving a signal from another access point, wherein the repetition rate identifies the another access point. The technique may also involve receiving at the access point an unmodulated impulse radio (IR) ultra wide band (UWB) pulse train from the another access point during a transmission interval associated with the repetition rate. The technique may also involve synchronizing a first clock associated with the access point to a clock associated with the another access point based on the received unmodulated IR UWB pulse train.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support local light biasing for silicon photomultiplier (SiPM)-based photodetectors used in optical wireless communication (OWC). In a first aspect, a photodetector may include a silicon photomultipier (SiPM) having an input sensor configured to detect a light signal and an output interface configured to produce an output signal proportional to an intensity of the light signal detected at the input sensor, and a controllable light source positioned to emit a biasing light signal within a field of view of the input sensor, wherein the controllable light source is configured to emit the biasing light signal within a sensitivity range of the SiPM. When such photodetector is implemented in an OWC receiver, an analysis of the output signal allows the OWC receiver to adjust the biasing light at the controllable light source. Other aspects and features are also claimed and described.

Abstract: 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.
