Directing against a special interference signal, an improved algorithm is presented for the use of an adaptive canceller. By which not only the noise can be effectively cancelled but also the convergence can be speeded to some extent. The performance of adaptive canceller is thus improved under this interference environment. The feaslbility and the superiority of this algorithm are proved by strictly theoretical inference. As indicated by computer simulation, the output result of canceller obtained by using improved algorithm is obviously better than that obtained by conventional algorithm. The particularity of this improved algorithm is pointed out finally
