Abstract
In a communication network, a sending node transmits a message with a multi-segment preamble and data to a receiving node. The receiving node calculates characteristics of the sending unit, channel, or transmitted signal by processing preamble segments. Once an unknown characteristic is determined, a segment of the preamble can be eliminated or reduced in length for subsequent messages, which increases efficiency of the message transmissions.
