Interference Rejecting Receiver for SATCOM Systems (IRRSS)
Agency / Branch:
DOD / NAVY
There are many papers and articles written describing receiver design methods for many radios using closely spaced channels and large differences in signal levels. The receiver design is usually centered around filtering out adjacent signals and having a `linear' enough design so that Intermodulation Distortion (IMD) products don't degrade the receiver performance. Neither of these methods addresses interference in the desired receive channel, and if that is the case then usually the channel is avoided or categorized as a degraded channel. A problem with this approach is that if the interference is not constant, or comes and goes, then a potentially usable channel is labeled unusable and the overall system performance is compromised. The problem only becomes worse when there are potentially multiple signals that are in band.
