A method of processing a radio frequency signal includes: receiving the radio frequency signal at an antenna of a receiver device; processing, by a radio frequency front-end device, the radio frequency signal; converting, by an analog-to-digital converter, the analog signal to a digital signal; receiving, by a neural network, the digital signal; and processing, by the neural network, the digital signal to produce an output.

An apparatus of a user equipment (UE) comprises a memory to store a Unified Radio Application and to store one or more configuration parameters for the Unified Radio Application, and one or more baseband processors to receive a radio application update from a remote server, and to update the Unified Radio Application via a Multiradio Interface (MURI) “updateRadioApps” operation with the received radio application update. One or more of the configuration parameters are maintained in the memory after the update.

Systems and methods for detecting radio frequency (“RF”) signals and corresponding origination locations are disclosed. An RF sensor device includes a software-defined radio and an antenna pair for receiving RF signals. Furthermore the RF sensor device may include a processing unit for processing/analyzing the RF signals, or the processing unit may be remote. The system calculates a phase difference between an RF signal received at two separate antennas of an antenna pair. The phase difference, the distance between the antennas, and the frequency of the RF signal are used for determining the origination direction of the RF signal. In various embodiments, the origination direction may indicate the location of a UAV controller or base station. The software-defined radio may include more than one antenna pair, connected to multiplexers, for efficiently scanning different frequencies by alternating active antenna pairs. Moreover, the system may execute packet-based processing on the RF signal data.

Antenna elements support RF communication over a communication link using frequency channels, RF processing circuits, and configuration circuitry to apply a selected configuration. Each configuration identifies processing circuit to antenna element couplings, and which frequency channel is allocated to each RF processing circuit. A reinforcement learning process is applied to dynamically alter which configuration to apply as a currently selected configuration. The reinforcement learning process maintains a future rewards record having entries that maintain, for an associated combination of link state and configuration, an estimated future rewards indication determined using a discounted rewards mechanism. A selection policy selects a configuration for a current link state, and then a new reward is observed that is dependent on how the selected configuration alters a chosen performance metric for the communication link. The estimated future rewards indication is updated by storing in the associated entry a predicted estimated future rewards indication generated by assuming, when using the discounted rewards mechanism, that all rewards that will be used in future to update the estimated future rewards indication in the associated entry will have the same value as the new reward.

A transmitter in a wireless communication network comprises a Carrier Interferometry (CI) coder and a multicarrier modulator communicatively coupled to the CI coder. The CI coder encodes a plurality of data symbols with a plurality of CI codes to produce a plurality of CI symbol values, wherein each of the plurality of CI symbol values equals a sum of information-modulated CI code chips. Each information-modulated CI code chip equals a CI code chip multiplied by one of the plurality of data symbols. The modulator modulates each CI symbol value onto a different subcarrier frequency to produce a multicarrier signal.
