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: Methods, systems, and devices are described for deriving an identifier encoded in a visible light communication (VLC) signal. One method includes capturing a first part of the VLC signal; extracting, from the first part of the VLC signal, a first pattern of bits representing at least a portion of the identifier encoded in the VLC signal; comparing the first pattern of bits to different portions of a plurality of identifiers; and identifying, based at least in part on the comparing, a subset of the plurality of identifiers as candidate matches to the identifier encoded in the VLC signal.

Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method to decode a visible light communication (VLC) signal by capturing images of a light source emitting a light modulated signal comprising a temporal sequence of symbols to determine decoded symbols and to further determine at least one codeword from a list of candidate codewords.

Abstract: Methods, systems, apparatuses, and devices are described for transmitting and receiving data using rateless visible light communication (VLC). A codeword having a plurality of symbols is identified. The codeword is repetitively transmitted in a VLC signal while, from one transmission of the codeword to a next transmission of the codeword, imparting changes in timings of the symbols of the codeword relative to a timing reference of an image capture frame of an image sensor configured to receive the codeword. A VLC signal including repetitions of a codeword is received. The codeword has a plurality of symbols. A determination is made regarding whether at least one symbol of the codeword is undetected in a repetition of the codeword. Upon determining that the at least one symbol is undetected in the repetition of the codeword, at least one other repetition of the codeword is searched to detect the at least one symbol.
