A computer-program product, a system, and a computer-implemented method include a processor(s) obtaining a configuration of a network including configurations of multiple network nodes and configurations of the network communication devices. The program code automatically models the network to generate a system model. The program code derives, from the system model, a loop-free Bayesian inference model, by generating a loop-free Bayesian network from the network.

Independent situational awareness for a network

A system and method for channelization of a wideband radio frequency signal into multiple narrowband channels includes obtaining, a dual-banded optical signal, where the dual-banded signal is a translated wideband radio frequency signal, and where the dual-banded signal includes a signal and an idler. The method also includes modifying, by the spectral phase mask, the spectral phases of at least one of the signal or the idler, where the modifying produces a spectral phase modulated output comprising at least one of a spectrally-modulated signal or a spectrally modulated idler. The method includes outputting, by the spectral phase mask, the spectral phase modulated output to an optical phase sensitive amplifier. The method includes receiving, by the optical phase sensitive amplifier, the spectral phase modulated output, and either amplifying or de-amplifying, by the optical phase sensitive amplifier, each component of the spectrally modulated output.

Photonics-based channelization enabled by phase-sensitive amplification

A system and method to optimize a multiple-input multiple-output signal processing RF communication system that includes obtaining, by a processor, at the receiver, during spatial processing, metrics from the channel stream. The metrics include a spatial correlation metric representing spatial coupling between multiplexed streams in the channel stream, a signal-to-noise power ratio metric representing propagation losses encountered by the signal, and a cross polarization discrimination metric representing whether polarization modes can be processed as independent groups. The processor obtains these metrics based on obtaining geometric information related to the receiver and the transmitter. Predictive methods may be employed to determine expectations for some metrics in advance. The method includes applying a policy with at least one objective of the system, and based on at least one metric and the policy, applying at least one adaptation to at least one of: the receiver or, the transmitter.

A system and method for selective wavelength interleaved filtering technique for analog to digital conversion (ADC) comprises a remote aperture for analog input, a modulator operable to transform the analog input into an initial optical signal, a photonic front end having high resolution optical filters operable to filter the optical signal into multiple subsequent optical signals and supply local oscillators for downconversion into electrical signals, a segmented subsystem having a plurality of ADCs, each operable to receive and convert one subsequent optical signal of the optical signals, and a memory buffer and process subsystem operable to reconstruct the converted subsequent optical signals into a digital representation of the analog input by executing reconstruction algorithms. Provision is made for compensation of distortions arising in the electrical to optical to electrical conversion process. The optical filters can include a self-registered filter wherein individual passbands are intrinsically aligned to one another.
