<p>This invention relates to a method of canceling interference. A mobile communication system using a smart antenna can resolve various multipath propagation interference with the method. The method includes steps: performimg beam-patterning on digital signal output from the receiver based on the smart antenna, obtaining a group of digital signals NRK (m); canceling mainpath signals, which contain in NRK (m), from other users, obtaining another group of digital signals NSK (m) containing only desired signals and all interference; searching NSK (m) to find all multipath interference signa ls from other user; canceling other multipath interference signals; superposing mainpath signals and individual multipath signal, obtaining digital signals that the interference has been canceled.</p> |
