An apparatus for a low-power radar detection (LPRD) receiver is proposed in this disclosure. The LPRD receiver comprises an analog-to-digital converter (ADC) circuit configured to receive an analog dynamic frequency selection (DFS) signal associated with a DFS channel in a DFS frequency band to generate a digital DFS signal. The ADC circuit comprises a finite impulse response (FIR) filter circuit configured to sample the analog DFS signal at an FIR sampling rate determined based on a predetermined frequency plan associated with the DFS frequency band to generate a sampled DFS signal; and an ADC conversion circuit configured to convert the sampled DFS signal to the digital DFS signal at an ADC conversion rate that is lower than the FIR sampling rate.

A low-power scouting receiver is presented that provides an ability perform low-power scouting functions at a relatively low power. The low-power scouting functions determine context information for the receiver and enable fine-tuning of other receiver operations based on the context information. The low-power scouting functions include receiver control and switching, jammer detection, self-interference detection, or other context-dependent radio parameters.

Dynamic frequency selection (DFS) is often a requirement for a wireless local area network (WLAN) apparatus to prevent the apparatus from interfering with other systems that have a priority to a radio frequency (RF) channel. When DFS is executed, the WLAN apparatus ceases WLAN operations on the channel and searches for an open channel to resume WLAN operations. Often a WLAN apparatus misinterprets signals from another system as operating on the channel when actually the received signals are signals leaked into the channel from a system transmitting on a different channel. Presented herein are methods and apparatuses for preventing unnecessary DFS operations resulting from misinterpreted signals through the use of a signal to noise ratio determined from a pulse spectral density of the received signal.

Various examples are provided for jamming avoidance response (JAR), and photonic implementations thereof. In one example, a method includes generating optical pulses that correspond to raising envelope of a beat signal associated with an interference signal and a reference signal; generating optical spikes that correspond to positive zero crossing points of the reference signal; providing a phase output that indicates whether the beat signal is leading or lagging the reference signal, the phase output based at least in part upon the optical spikes; and determining an adjustment to the reference frequency based at least in part upon the optical pulses and the phase output. In another example, a JAR system includes a photonic P-unit to generate the optical pulses; a photonic ELL/T-unit to generate the optical spikes; a photonic TS unit to provide the phase output; and a logic unit to determine the adjustment to the reference frequency.

In order to avoid various jamming attacks from intelligent jammers in modern complex wireless environments, a system and method is presented for a user radio to generate and implement an adaptive anti-jamming communication strategy. The said adaptive anti-jamming communication strategy is obtained via the training process for a specific neural network using Deep Double-Q Reinforcement learning algorithm in the strategy generation phase. The objective of this process is to discover a strategy to select the optimal radio action including transmission channel and transmission power for the user radio, which is changed adaptively to different jamming patterns to maximize the successful transmission rate (jamming-free) while retaining the power consumption of user radio as low as possible. In the strategy implementation phase, the user radio chooses an appropriate radio action based on output of trained neural network after the training process; thus, achieves robust and efficient communications against diverse complex jamming scenarios.
