Abstract: Provided herein are systems and methods for synchronizing clocks and determining a range distance between two clocks using one or more timing signals that are communicated between the clocks. The determination can be made to also account for movement between the clocks such as if the clocks are converging (i.e., the distance between them is decreasing over time) or diverging (i., the distance between the clocks is increasing over time.) The systems and methods can utilize timing signals transmitted between two clocks that are synchronizing with another using the precision time protocol. In order to account for the increasing or decreasing distance between the clocks, the systems and methods can utilize Doppler shift data taken between the clocks to apply a correction factor to the timing signals. The timing signals and correction factor can be utilized to also determine a range distance between the clocks.

Abstract: Methods, systems, and devices are described for transmitting an identifier using visible light communication (VLC) and for generating a plurality of identifiers for transmission using VLC. Input identifying an illumination factor associated with a light source is received. A first set of modulation parameters is modified for transmitting the identifier using VLC. The first set of modulation parameters is modified based on the illumination factor. A signal, in which the identifier is encoded, is applied to the light source. The signal is applied according to the first set of modulation parameters. Another method includes identifying a number of light transmitting devices, generating a plurality of identifiers based on the identified number of light transmitting devices, storing the generated identifiers, determining a plurality of cyclic shifts for each identifier in the plurality of identifiers, and removing identifiers from the plurality of identifiers that match the identified cyclic shifts.

Abstract: Data is received from a physical coding sublayer (PCS) of a physical layer, where the physical layer comprises a BASE-R physical layer. The data is used to generate a forward error correction (FEC) block comprising a shortened cyclic code comprising 32 rows of a particular number of bits, the particular number of bits comprise payload bits generated from output of the PCS and one or more bits of transcoding overhead, wherein the FEC block further comprises 32 parity bits at the end of the FEC block. The FEC block is scrambled using a pseudo-noise sequence. The FEC block is sent to a physical medium attachment (PMA) sublayer of the physical layer.

Abstract: A data source sends a synchronization signal and information to several data sinks that use the synchronization signal and a specified parameter to determine when to process the information. The data source and data sinks may comprise wireless nodes such as, for example, a wireless audio source that sends multi-channel data to a pair of wireless earpieces. The wireless earpieces use the synchronization signal and a latency interval to determine the appropriate time to output audio based on the audio channels.
