Patent 7738355 was granted and assigned to Entropic Communications on June, 2010 by the United States Patent and Trademark Office.
In a communication network, a sending node transmits a message with a multisegment 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.
