  • Adaptive noise suppression for digital modems
    Patent number: 4633485
    Abstract: This invention provides a receiver for a QAM modem with a phase tracking loop for eliminating phase errors due to phase jitter and frequency offset. The instantaneous phase error of the received signal is monitored and if it is below a certain preselected value, indicating the presence of white noise, the gain of the phase tracking loop is reduced.

  • Gain tracker for digital modem
    Patent number: 4631738
    Abstract: A phase and gain corrector is described for a modem for receiving QAM or PSK-encoded signals. An ideal vector corresponding to the received vector is generated and the difference or error vector is resolved into a radial component in the direction of the ideal vector a tangential component. A gain corrector and a phase corrector variable are calculated from said radial and tangential components of the error vector and used to correct the gain and phase of the received signals.
