摘要： Systems and methods for operating a system. The methods may comprise: using a machine learning model to identify which frequency of a plurality of possible frequencies that can be used by a communication device for wireless communications is an inferred best frequency based on weather report information and/or predicted weather information; performing operations to select a best frequency from the plurality of possible frequencies using the inferred best frequency and a frequency value selected by a link establishment process of the communication device; and causing the communication device to communicate signals with the best frequency which was selected.

摘要： Reducing harmonics in a radio transmitter can involve using an electronically tunable harmonic filter (ETHF) in a transmit path at the output of an RF power amplifier stage to reduce harmonic signal components in the RF transmit signal. At least one filter characteristic of the ETHF is selectively controlled using one or more RF switch. The one or more RF switches that are used to control the ETHF can include a CMOS-SOI and/or a MEMs type of switch. Various filter characteristics of the ETHF can be controlled including a bandwidth and/or a center frequency of the ETHF.

摘要： A radio frequency (RF) communications system may include an RF transmitter having multicarrier transmitter circuitry that transmits frequency bands over a frequency range. A controller may selectively transmit real information over at least one of the frequency bands and selectively transmits fake information within the frequency range. The controller's operation is based on embedded machine learning model and real-time effectiveness feedback from built-in spectral analyzer. An RF receiver receives the real information from the RF transmitter.

摘要： A portable radio may include a radio frequency (RF) transmitter, an RF receiver, and an audio input transducer. A controller may store command messages and speech messages, implement a stand-alone, speech recognition and text-to-speech (TTS) function for the stored command messages and stored speech messages. The controller may also control at least one of an RE transmitter and RF receiver of a remote radio based upon an input command matching one of the stored command messages using the audio input transducer and the stand-alone speech recognition and TTS function, and convert a speech message matching one of the stored speech messages into a text message. The RF transmitter may send the text message to the remote receiver.

摘要： Systems and methods for operating a communication device. The methods comprise: concealing the communication device and/or at least one cable in a ballistic wearable item (e.g., a ballistic vest) such that the communication device resides in a storage slot for a trauma plate, where the communication device comprises a frame having a cross-sectional profile that matches a cross-sectional profile of the trauma plate by a given amount (e.g., 75-100%); and performing communication operations by a radio module integrated with the frame of the communication device.

摘要： A radio frequency (RF) communication device includes an RF spectral sensor that senses a dynamically changing RF spectral environment, and RF circuitry having at least one settable parameter. A controller dynamically sets the at least one settable parameter thereby affecting power consumption and RF communication performance by using an artificial intelligence (AI) model based upon the power consumption and the RF communication performance in the dynamically changing RE spectral environment.

摘要： Systems (400) and methods for removing dither introduced into a transmitted RF signal. The method comprising: receiving, by a receiver, the transmitted RF signal; converting, by the receiver, the transmitted RF signal into a discrete-time IF signal comprising a sequence of samples, where at least a first sample of said samples has a first sample duration different than a second sample duration of at least a second sample of said samples; and performing operations by a sub-sample dither removal device of the receiver to modify a sample timing of the discrete-time IF signal by decreasing or increasing the first sample duration of the first sample using a digital signal processing technique in a digital domain.

摘要： Systems and methods for reducing detection and interference of signals communicated from a communication device. The methods comprise: coupling an RF-to-FSO converter to a port of the communication device; providing a first radio frequency signal from the communication device to the RF-to-FSO converter via the port; using the first radio frequency signal by the RF-to-FSO converter to modulate an optical signal; and emitting the modulated optical signal from the RF-to-FSO converter through free space.
