Systems, methods, and devices are disclosed herein for Doppler based position estimation. Systems may include an antenna configured to receive a radio frequency (RF) signal from an emitter, and configured to generate an output signal based on the received RF signal. Systems may also include a receiver configured to receive the output signal from the antenna. The receiver may include one or more processors configured to identify a plurality of initial conditions for a plurality of state variables associated with the emitter, obtain a measurement of the RF signal from the emitter and an estimate of an uncertainty associated with the measurement, and generate an output based, at least in part, on an updated estimate of the plurality of state variables, the output identifying a position, velocity, and carrier frequency of the emitter. Systems may also include a communications interface configured to communicatively couple the antenna with the receiver.

An improved system for providing transparent, in-line encryption of data-at-rest (DAR) stored by a host controller of a host device. An encryption core is instantiated in a hardware device physically coupled to a system board within the host device. The encryption core includes a storage device proxy, an encryption engine, and a plurality of host device proxies. Each host proxy among the plurality of host proxies interfaces the host controller to one persistent storage device among a plurality of persistent storage devices within the host device via the storage device proxy. The storage device proxy exposes the plurality of persistent storage devices to the host controller as a single persistent storage device. The encryption core encrypts and decrypts DAR exchanged between the host controller and an encrypted storage device.

Data-at-rest (DAR) encryption for integrated storage media

A method and apparatus for processing a number of profiles for a software defined radio is provided. In one illustrative example, an apparatus comprises a pre-compiler and a compiler. The pre-compiler is configured to receive a number of profiles for the software defined radio in a first format. The pre-compiler is further configured to form a number of profile structures in a second format during build time based on the number of profiles. A profile structure in the number of profile structures corresponds to a profile in the number of profiles and includes a set of substructures comprised of a number of dynamic substructures and a number of static substructures. The compiler is configured to convert the number of profile structures into compiled code during the build time for use in deploying a set of components on the software defined radio at runtime.
