Abstract
A method of and device for recognizing a network-synchronous interfering signal during a data transmission in which pauses occur between useful signals, with the duration of a shortest pause being Tp and a main frequency being f are disclosed. The method includes the steps of defining a time span Td being shorter than the shortest pause Tp, but longer than the longest period 1/f or ½ f, of a network-synchronous interfering station; determining whether pauses occur that are longer than Td during a time period T check>Td; and interpreting an occurrence of pauses as the presence of a useful signal without a network-synchronous interfering signal, and interpreting a lack of an occurrence of pauses as the presence of an interfering signal.
