1. A receiver of a communications system, the receiver comprising:
a first burst detector configured to receive a digitized signal transmitted over a channel and to generate a first burst indicator by analyzing a physical structure of the receive digitized signal to determine whether a burst is present in the received digital signal; and
a second burst detector configured to generate a second burst indicator by analyzing an informational structure of a decoded signal that corresponds to the received digital signal to determine whether a burst is present in the received digital signal,
wherein the first burst detector analyzes the physical structure of the received digital signal using a data-aided analysis based on known pilot symbols, the known pilot symbols comprising ambles of the received digital signal.
