ABSTRACT:
In a digital communication system, communication units may reduce power consumption while attempting to detect reception of valid data by sampling and filtering a data stream at a first sampling rate producing a first filtered data stream. When the first filtered data stream indicates potential valid data, the communication unit samples and filters the data stream at a second sampling rate, wherein the second sampling rate is greater than the first sampling rate and consumes more power, producing a second filtered data stream. The communication unit determines whether the data stream contains valid data based on the second filtered data stream.
