Method for detecting the eventual presence of an interferer, for example a radar signal, adapted to interfere with a wireless device, for example an UWB device, and corresponding device
First Claim
1. A method for detecting the presence of an interferer capable of interference with a wireless device, the wireless device including at least one receiving chain and an associated analog to digital conversion (ADC) stage, the method comprising:
- receiving an incident signal on the receiving chain;
delivering to the ADC stage an analog signal generated from the incident signal and providing a binary signal representative of the level of the analog signal;
determining binary information from the binary signal provided by the ADC stage, the binary information including a first value and a second value; and
analyzing a temporal evolution of the binary information to detect the presence of the interferer and comprising detecting the occurrences of the first value and generating an analysis information representative of a temporal evolution of the occurrences, and comparing the analysis information with reference information representative of the interferer;
wherein generating the analysis information comprises counting the amount of successive first values and determining an occurrence frequency of successive packets including successive first values.

Abstract
The method is for detecting the eventual presence of an interferer that is adapted to interfere with a wireless device. The wireless device is provided with at least one receiving chain including an analog to digital conversion stage. The method includes receiving on the receiving chain an incident signal, and delivering to the ADC stage an analog signal from the incident signal. The method further includes elaborating or determining a binary information from a binary signal delivered by the ADC stage and representative of the level of the analog signal, analyzing a temporal evolution of the binary information and detecting the presence of the interferer from the analysis.
