Abstract
The present invention relates to the field of communication technology, and provides a method and a device for eliminating interference in a mobile communication system. The method comprises: step 1: re-constructing signal estimation {circumflex over (d)}of inter-symbol interference and multi-access interference in accordance with an output signal {circumflex over (d)}from an equalizer; and step 2: performing interference elimination on the inter-symbol interference and multi-access interference in an output signal êfrom a matched filter in accordance with the signal estimation {circumflex over (d)}of inter-symbol interference and multi-access interference, to obtain signal estimation {circumflex over (d)}with the interference eliminated. According to the present invention, it is able to eliminate the impact of an interference signal and improve the receptivity of a receiver for a useful signal.
