<p>The invention relates to an interference cancellation method and a receiver comprising interference cancellation means (400) for suppressing a narrow-band interference signal from a received signal, means (400) for performing an orthonormal conversion of the signal into subspace components of a desired subspace, a decoder (402) connected operationally to the output of the interference suppression means (400), in which decoder an estimate for the received signal is obtained. The output of the decoder is operationally connected to the interference suppression means, and the conversion means are arranged to determine an estimate for narrow-band interference properties, in which determination the estimate obtained from the output of the decoder is substracted from the received signal before the orthonormal conversion is performed. By using the determined estimate, the interference cancellation means (400) are arranged to reduce effect of the subspace components comprising narrow-band interference signals from the received signal.</p> |
