    摘要： A full-duplex transceiver is provided with componentry and methods for cancellation of nonlinear self-interference signals. The transceiver is capable of receiving an incoming radio-frequency signal that includes both a desired radio-frequency signal component and a self-interference component caused by the transceiver's own radio-frequency transmission. The transceiver demodulates the incoming radio-frequency signal to generate a first demodulated signal. The transceiver combines an analog corrective signal with the first demodulated signal to generate a second demodulated signal with reduced self-interference. The transceiver processes the first and second demodulated signals to determine a desired incoming baseband signal and to determine nonlinear components of the self-interference signal, such as nonlinearities introduced by the transceiver's power amplifier.

    摘要： In a coherent optical receiver receiving a polarization multiplexed optical signal through an optical communications network, a method of compensating noise due to polarization dependent loss (PDL). A Least Mean Squares (LMS) compensation block processes sample streams of the received optical signal to generate symbol estimates of symbols modulated onto each transmitted polarization of the optical signal. A decorrelation block de-correlates noise in the respective symbol estimates of each transmitted polarization and generating a set of decorrelated coordinate signals. A maximum likelihood estimator soft decodes the de-correlated coordinate signals generated by the decorrelation block.

    摘要： A server performed method includes receiving, from a first device, a request for authentication by the server, wherein the request includes a unique identifier of the first device, and upon verifying that the unique identifier is registered at the server, sending a push notification to the first device and to a second device registered as associated with the first device. A first list of IDs of at least one wireless device within wireless communication range of the first device is received from the first device, and a second list of IDs of at least one wireless device within wireless communication range of the second device is received from the second device. The first and second list of IDs are compared to identify common IDs between the first list and the second list. Successful authentication of the first device is confirmed when at least one common ID is identified.

    摘要： Embodiments include a method for secure data storage including constructing an encryption key from a plurality of key elements, the constructing including distributing the plurality of key elements to a plurality of key maintenance entities, each of the plurality of key maintenance entities employing a plurality of independent safe guards for their respective key elements of the plurality of key elements; and requiring access to the plurality of key elements to construct the encryption key. The method includes receiving a subset of the plurality of key elements via a twice-encrypted communications channel; and regenerating the encryption key at the client node; and after encrypting data, deleting the subset of the plurality of key elements received over the twice-encrypted communications channel, retaining any of the plurality of key elements previously stored at the client node.
