NOISE INGRESS CANCELATION |
| 摘要 |
A demodulator can include an ingress exciser configured to remove ingress noise from a burst mode digital input signal that is above a predetermined threshold and resides within a narrowband. An adaptive equalizer can be configured to adaptively equalize an estimate of the signal provided from the ingress exciser and to provide an adaptively equalized signal. An ingress predictor can be configured to subtract an estimate of remaining predicted ingress noise from the adaptively equalized signal to provide a resultant signal that is substantially free of the ingress noise. |
