Abstract:
A method for evaluating, by an radio frequency identification reader (1), a data stream signal (DS) in respect of data and/or collision, comprises comparing the data stream signal (DS) with at least one threshold level, particularly a data bit level and/or a collision level, and evaluating the results of the comparison, wherein both the threshold level and its adaptation speed (α(n)) are adapted in dependence of the course of the data stream signal (DS) and/or the course of said threshold level.
