A receiver is suitable for use in a wireless communications system, which is subject to interference from interfering signals having much narrower bandwidths than the wanted signal. In the receiver, an interfering signal is detected in the frequency domain and moreover, the cancellation also takes place in the frequency domain. Detection and cancellation in the frequency domain also provides a way of estimating the magnitude of the interfering signal, and hence also allows the wanted signal, at the frequency of the interfering signal, to be estimated.
