METHOD AND DEVICE FOR ELIMINATING INTERFERENCE IN MOBILE COMMUNICATION SYSTEM

摘要

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 d MAI + ISI of inter-symbol interference and multi-access interference in accordance with an output signal d esb from an equalizer; and step 2: performing interference elimination on the inter-symbol interference and multi-access interference in an output signal ê MF from a matched filter in accordance with the signal estimation d M AI + ISI of inter-symbol interference and multi-access interference, to obtain signal estimation d JD+IC 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.
