Abstract
Symbols are received on a downstream channel. A value of a channel synchronization parameter is determined based on the received symbols. An interference event on the downstream channel is detected. In response to detecting the interference event: an output signal is determined based on at least one cached value of the channel synchronization parameter, the at least one cached value being determined based on symbols received prior to and offset from the detecting of the interference event.
Claims8
A device, comprising:
- a receiver configured to receive symbols on a downstream channel, and
- at least one circuitry configured to detect an interference event on the downstream channel,
- wherein the at least one circuitry is configured to determine a first phase gradient based on a symbol received at a first point in time prior to a start point of the interference event and to determine a second phase gradient based on a symbol received at a second point in time subsequent to an end point of the interference event,
- wherein the at least one circuitry is configured to determine a timing drift between the first point in time and the second point in time based on the first phase gradient and the second phase gradient.
