Abstract:
1. A method of assessing a radio frequency (RF) interferer, the method comprising: processing a baseband signal to generate hard-decision samples of at least ones and zeroes, wherein the baseband signal comprises a downconverted desired signal and a downconverted interferer, the downconverted desired signal corresponding to a desired signal and the downconverted interferer corresponding to the RF interferer; observing a plurality of consecutive ones or zeroes to tabulate run lengths of ones or zeroes from the hard-decision samples, and collecting a frequency of occurrence distribution of the run-lengths observed; and inferring at least one of an RF frequency of the RF interferer or a signal strength of the RF interferer relative to a signal strength of the desired signal based at least partly on the collected frequency of occurrence distribution.
