The invention comprises an array of ADCs, associated either with spatially separated signal input devices such as for example antennae, or with a single signal input device and a plurality of filters having a variable phase delay, which provide a digital output which is processed to remove spurious signals introduced by the ADCs thereby providing a linearised output. An array of N antennae with respective band pass filters and ADCs () feeds received signals into a frequency channelisation device () which divides each of the N input streams into M lower bandwidth streams for distribution. In a first path, an FFT () is used to detect signal of interest, to determine where intermodulation products arm likely to exist and to provide course data for the spatial processing used in the signal separation sub-systems. The second path () includes the detection and separation of co-channels signals. Signal classification techniques are then used to identify spurious sir, which are then removed.
