  • Patent number: 5479453
    Abstract: A digital receiver for receiving an RF signal has a conventional RF to intermediate frequency (IF) converter. The IF signal, however, is amplified with a limit on its amplitude. In addition, a Receive Signal Strength Intensity (RSSI) signal is generated. The RSSI signal contains the envelope information of the modulated IF signal. The IF amplitude limited signal containing phase information, is then digitized and a complex baseband signal is produced. The complex baseband signal is then combined with the RSSI signal to restore the amplitude information of the modulated IF signal in the complex baseband signal. The restored complex baseband signal can be equalized with a conventional equalizer to remove intersymbol interference. A conventional symbol detector detects the symbol in this signal stream.
