Ingress cancellation is a method for removing narrowband noise from an electromagnetic signal using a digital filter.[1] This type of filter is used on broadband networks that are based on hybrid fiber-coaxial cable.[2][3]
If a carrier appears in the middle of the upstream data signal, ingress cancellation can remove the interfering carrier without causing packet loss.[citation needed]
Ingress cancellation also removes one or more carriers that are higher in amplitude than the data signal. Ingress cancellation eventually will break if the in-channel ingress gets too high.[citation needed]
