Claim:
1. A communication system, comprising: an analog device configured to produce an electrical analog domain signal within a corresponding frequency band representing a superposition of: a received signal containing information, and at least one intermodulation distortion product of components of the received signal within the frequency band, the at least one intermodulation distortion product being interfering with demodulation of the information contained in the received signal, and non-filterable from the received signal by frequency-domain filtering without loss of the information contained in the received signal; a digitizer configured to quantize the electrical analog domain signal; at least one memory configured to store information corresponding to parameters of a model of intermodulation distortion properties of the analog device; and a digital signal processor configured to receive the quantized electrical analog domain signal, read the stored information from the memory, process the quantized electrical analog domain signal to attenuate a digital representation of the at least one intermodulation distortion product with respect to a digital representation of the received signal, selectively dependent on the model of intermodulation distortion properties of the analog device, the representation of the at least one intermodulation distortion product being attenuated substantially without loss of the information contained in the received signal.
