This paper improves two kinds of nonlinear interference canceller,that is,successive interference canceller and parallel interference canceller and adds the adaptive filter factor to them so as to improve these two cancellers' performances.Through Matlab simulation,the result shows that in the same condition,adaptive interference canceller improves considerably in the bit error rate compared with the original interference canceller,and the intrinsic defects of error accumulation in orrginal interference canceling algorithm can be eliminated.
