Abstract:
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.
