<p>A radio receiver 1 has a device for reducing interference in an r.f. received signal, for example an HF signal conveying high speed data, comprising a channel estimator 3 for estimating the transmitted signal by comparing the received signal with locally generated signals processed in dependence on the response of the communication channel, together with a filter 2 for filtering interfering signals from the received signal. The use of the channel estimator for compensating for the response of the communication channel as opposed to an equaliser enables interfering signals to be filtered from the received signal. <IMAGE></p> |
