SYSTEM AND METHOD FOR COMMUNICATING DATA USING WAVEFORM WITH EXTENDED PREAMBLE

摘要

A system communicates data and includes an encoder for encoding communications data. A modulator maps the communications data based on a specific mapping algorithm to form a communications signal over which the communications data can be transmitted. The communications signal includes a preamble that has set up or transmission parameters used for acquiring the signal at a modem and at least one extended preamble for conveying additional set up or transmission parameters. This extended preamble includes N extended preamble bits having at least one of information, transmission parameter and control bits and M map bits that identify a predetermined mapping for the N extended preamble bits.
