Abstract: Data management systems and methods include a cloud-based platform coupled to a system of agents or folders hosted on client devices. The platform does not store actual data but instead makes use of metadata provided by the agents to track a location of all data in the system and manage the distributed storage, movement and processing of the actual data among the agents. In so doing, the platform pools networked storage into “virtual clusters” using local storage at the agents. The agents collectively monitor, store, and transfer or move data, and perform data processing operations as directed by the platform, as described in detail herein. The agents include agents hosted on or coupled to processor-based devices, agents hosted on devices of a local area network, agents hosted on devices of a wide area network, agents hosted on mobile devices, and agents hosted on cloud-based devices.

Abstract: A method for optimizing uplink performance of Open Radio Access Network (O-RAN) system implementing O-RAN split option 7-2x-based uplink (UL) multiple-input multiple-output (MIMO) operation includes: selectively utilizing non-port reduced DMRS symbols and non-port reduced DMRS measurements to mitigate performance degradation of the UL MIMO in conditions involving high mobility for a user equipment (UE) and/or high interference. The non-port reduced DMRS symbols are DMRS symbols from multiple antenna streams before digital beamforming operation, and non-port reduced DMRS measurements are measurements derived from the non-port reduced DMRS symbols. A radio unit (RU) of the O-RAN system i) extracts the non-port reduced DMRS symbols, and ii) transmits the non-port reduced DMRS measurements to a distributed unit (DU) of the O-RAN system. The DU transmits combining and/or digital beamforming matrix elements to the RU for combining and/or digital beamforming matrix application.

Abstract: Disclosed herein are systems and methods for estimating target ranges, angles of arrival, and speed using optimization procedures. Target ranges are estimated by performing an optimization procedure to obtain a denoised signal, performing a correlation of a transmitted waveform and the denoised signal, and using a result of the correlation to determine an estimate of a distance between the sensor and at least one target. Target angles of arrival are estimated by determining ranges at which targets are located, and, for each range, constructing an array signal from samples of received echo signals, and using the array signal, performing another optimization procedure to estimate a respective angle of arrival for each target of the at least one target. Doppler shifts may also be estimated using another optimization procedure. Certain of the optimization procedures use atomic norm techniques.

Abstract: An integrated circuit (IC) features a delay-locked loop (DLL) with a DLL signal input. The DLL comprises a delay line with multiple delay stages, a gater with clock input, and a phase-frequency detector (PFD). The delay line's signal input is linked to the DLL signal input, while the gater's inputs are connected to phase outputs of the delay line. The gater's clock input is tied to the DLL signal input, and its outputs feed into the PFD inputs. The PFD generates outputs that are used by a loop filter to control the speed of the delay line.

Abstract: Superconducting integrated circuits may advantageously employ superconducting resonators coupled to a microwave transmission line to efficiently address superconducting flux storage devices. In an XY-addressing scheme, a global flux bias may be applied to a number of superconducting flux storage devices via a low-frequency address line, and individual superconducting flux storage devices addressed via application of high-frequency pulses via resonators driven by the microwave transmission line. Frequency multiplexing can be employed to provide signals to two or more resonators. A low-frequency current bias may be combined with a high-frequency current in one or more superconducting resonators to provide Z-addressing. A low-frequency current bias may be combined with a high-frequency current in one or more superconducting resonators to eliminate a flux bias line.
