摘要： Network throughput can be increased and the message failure rate can be reduced in 5G and 6G communications by use of AI-based fault mitigation: that ism detection, localization, and correction of faulted message elements in real-time. A receiver provides the demodulated message, along with amplitude and phase measurements of each message element, directly to a properly trained artificial intelligence model. The model determines the most-likely faulted message elements, and in some cases can indicate the most probable correct value of the faulted message elements. The AI model can also determine the fault probability of each message element. The expected message content (such as value ranges and predetermined format) can also be provided to the AI model, for further corruption sensitivity. By correcting faulted messages in less time than required for a retransmission, the system can save time, reduce backgrounds, and greatly reduce dropped messages.

摘要： A radio frequency (RF) test device such as a spectrum analyzer may include an RF attenuator to attenuate a received RF signal; a mixer to down-convert the attenuated RF signal; an IF attenuator to attenuate the down-converted signal; an analog-to-digital converter (ADC) to digitize the attenuated, down-converted signal; and a processor, which may select attenuation values for one or more of the RF attenuator and the IF attenuator based on an error magnitude vector (EVM) analysis, an RF signal type, and/or a signal level at an input of the ADC. The processor may use a look-up table for the selection. Initial attenuation values may be selected based on an expected RF signal type, RF signal frequency, and/or RF signal bandwidth. The attenuation values may also be selected in an iterative manner stepping the attenuation values up or down.

摘要： Technology described herein can gather and statistically analyze time domain power data for enabling real-time adjustment of one or more parameters of a radio system. In an embodiment, a system can comprise a processor and a read circuit communicatively coupled to the processor, wherein the processor controls the read circuit to read power data in a time domain from a radio system, and an analysis component communicatively coupled to the processor, wherein the analysis component compares the power data in the time domain to a power threshold, and wherein, based on a result of the power data being compared to the power threshold, the analysis component sorts the power data into bins at a storage component communicatively coupled to the processor.

摘要： A method of error vector magnitude, EVM, minimization for a radio frequency, RF, measurement equipment is provided. The method comprises: measuring the EVM of a receive, RX, chain of the RF measurement equipment in accordance with a transmit, TX, feedback signal; and responsive to a trigger event, actuating one or more power-adjusting members interposed in the RX chain in accordance with the measured EVM of the RX chain. Among others, the RF measurement equipment is thereby consistently operated based on optimal power levels in the RX chain.

摘要： A method of calibrating an analog front end (AFE) filter of a radio frequency integrated circuit (RFIC) includes: making a first measurement of the RFIC at a first measuring frequency while the AFE filter is bypassed; generating a first amplitude estimate and a first phase estimate at the first measuring frequency using the first measurement; making a second measurement of the RFIC at the first measuring frequency while the AFE filter is turned on; generating a second amplitude estimate and a second phase estimate at the first measuring frequency using the second measurement; and calculating a frequency response of the AFE filter at the first measuring frequency, which includes calculating an amplitude response of the AFE filter based on the second amplitude estimate and the first amplitude estimate; and calculating a phase response of the filter based on the first phase estimate and the second phase estimate.
