Abstract

Selective compensation for interference in a communications system, such as a piconet or scatternet using an Industrial-Scientific-Medical (ISM) frequency band, may be achieved, according to embodiments of the present invention, by adapting the interference mitigation scheme applied in a communications system based on comparison with known patterns associated with particular types of interference, such as interference generated by microwave ovens, medical equipment, industrial equipment and wireless communications devices. According to embodiments of the present invention, a communications system, such as wireless communications system, detects interference and changes from a first interference mitigation scheme to a second interference mitigation scheme if the detected interference exhibits a pattern sufficiently correlated with predetermined pattern associated with a predetermined type of interference, such as the half-cycle pulsed pattern typical of a microwave oven.
