    Abstract: Methods, systems and devices for interference characterization and excision are described. An example method for wireless communication includes receiving, via an analog prefilter in a first frequency band, a first analog signal comprising a signal-of-interest and an interfering signal, receiving, via the analog prefilter, in an additional frequency band, an additional analog signal, wherein the additional analog signal comprises the interfering signal, generating, based on the additional analog signal, an estimate of the interfering signal, digitizing the first analog signal to generate a first digital signal, canceling the estimate of the interfering signal from the first digital signal to generate an estimate of the signal-of-interest, and demodulating the estimate of the signal-of-interest to generate estimated data symbols.

    Abstract: Devices, systems and methods for collaborative wireless communication in a wireless network are described. One example method includes performing a bidirectional communication with a reference node in the source cluster, receiving, from a destination cluster comprising a second plurality of nodes, a probe generated using a phase associated with the destination cluster, estimating, based on a propagation delay of the probe, a delay parameter, generating, based on the phase associated with the destination cluster and the delay parameter, a channel estimate, and transmitting, to each of the second plurality of nodes, a common message generated using a phase value and a delay value, wherein the phase value and the delay value are derived based on the channel estimate, and wherein the destination cluster is remotely located from the source cluster.

    Abstract: Devices, systems and methods for providing network-enabled connectivity for disadvantaged communication links in wireless networks are described. One example method for enabling connectivity over a disadvantaged link includes receiving, by a first node of a plurality of nodes from a source node in the first frequency band in a first timeslot, a first signal comprising a message, receiving, by the first node from at least a second node in a second frequency band in a second timeslot, a second signal that is used to generate a first reliability metric corresponding to the message, and performing, based on a plurality of reliability metrics corresponding to the message and the first reliability metric, a processing operation on the message, the first frequency band being non-overlapping with the second frequency band, and a duration of the first timeslot being greater than a duration of the second timeslot.

    Abstract: Methods and systems for improving authenticated encryption in counter-based cipher systems are presented. Embodiments of the present invention provide secure and efficient means to achieve both the authenticity and privacy goals of authenticated encryption, and are compatible with most block cipher modes of operation, e.g. CBC, CFB and CTR, and most symmetric-key cryptographic functions, e.g. AES, DES and RC5. In particular, using block cipher encryption with data-dependent initialization vectors achieve the privacy goal and enable over-the-air transmissions to remain uncompromised, especially in scenarios that may result in the counter being reset in counter-based cipher systems.

    Abstract: Methods and systems for improving communication in a multi-hop, time-slotted wireless network are presented. Embodiments of the present invention are able re-use timeslots to locally transmit information to one-hop nodes, thereby utilizing the bandwidth more efficiently. Other embodiments are able to evaluate the trade-off between power consumption and communication reliability, and are consequently able to provide increasing degrees of robustness for broadcasts in the wireless network. That is, these latter embodiments are able to incrementally use re-transmissions, therein trading-off battery life for an increased message completion rate or a lower packet error rate, for example, in order to reliably broadcast critical or high-priority message network-wide.

    Abstract: Devices, systems and methods for analog automatic gain control (AGC) based on estimated distributions of signal characteristics are described. One example method includes generating a digital measurement of a first signal characteristic based on a second signal characteristic of an input signal received by the device, where the second signal characteristic is based on a level of the input signal. The digital measurement of the signal characteristic is used to update a statistical model for the input signal and the posterior probability distribution of the second signal characteristic conditioned on previous digital measurements of the first signal characteristic. The updated posterior probability distribution is used to generate a gain estimate, which is then used to adjust the power level of the input signal. Another example method may use multiple statistical models for each waveform supported by the system.
