Abstract: Embodiments of a non-contiguous spectral-band modulator and method for non-contiguous spectral-band modulation are generally described herein. In some embodiments, an input symbol tuple may be mapped to a sequence of values. Each value of the sequence may represent an instantaneous frequency of a waveform for a signal with a power spectral density that is substantially constrained to the two or more subbands of a non-contiguous spectrum. The values of the se¬ quence of instantaneous frequency values may be accumulated and a phase-sample sequence representing phase samples of a transmit waveform may be generated. An exponentiation may be performed on the phase-sample sequence to generate a constant modulus signal sequence. An output signal sequence is generated that is constrained to a region in the complex plane, such as an annulus, when the signal is in a subband. The output signal sequence may be shaped to con¬ strain spectral energy during transitions between subbands.

Abstract: Systems and methods are disclosed herein for detecting a threat to a computing device (102). The system includes a server (106) and a computing device (102) in communication with the server (106) and configured to browse the Internet (104). The server (106) receives data indicating a configuration parameter of the computing device (102) and executes an emulation of the computing device (102) that replicates the configuration parameter. The server (106) also receives data relating to the computing device's browsing behavior and replicates the browsing behavior on the emulation. Upon detecting an undesired modification to the emulation of the computing device (102) caused by the replicated browsing behavior, the server (106) automatically generates and outputs an alert related to the undesired modification and related browsing behavior.

Abstract: An optical receiver may include a unitary transformation operator to receive an n-symbol optical codeword associated with a codebook, and to perform a unitary transformation on the received optical codeword to generate a transformed optical codeword, where the unitary transformation is based on the codebook. The optical receiver may further include n optical detectors, where a particular one of the n optical detectors is to detect a particular optical symbol of the transformed optical codeword, and to determine whether the particular optical symbol corresponds to a first optical symbol or a second optical symbol. The optical receiver may also include a decoder to construct a codeword based on the determinations, and to decode the constructed codeword into a message using the codebook. The optical receiver may attain superadditive capacity, and, with an optimal code, may attain the Holevo limit to reliable communication data rates.

Abstract: A technology is described for optical communication. An example of the technology can include receiving an event stream containing indications of independent events detected by pixels in an event camera. An event may be a change in brightness detected by a pixel in the pixel array, and the pixel independently generates an indication of the event in response to detecting the event. The event stream can be demultiplexed into a plurality of communication streams containing related events associated with a plurality of communication sources. The events contained in a communication stream can be aggregated based in part on an event proximity and an event time that associates an event with other events contained in the event stream. The plurality of communication streams can be demodulated to extract optically transmitted information from the plurality of communication streams, which can be sent to a data consumer.
