<p><P>PROBLEM TO BE SOLVED: To provide a communications system that uses adaptive baseband injected pilot carrier symbols. <P>SOLUTION: This system, and the related method and apparatus include a transmitter 200 that has an encoder 206 and a baseband modulator 210, that encodes and modulates a sequence of payload data symbols as a signal constellation for communication. An amble generator 216 and a baseband modulator 218 generate amble symbols as a known sequence of M symbol times in length every N symbol times. A multiplexer 212 multiplexes the data and amble symbols together, to generate a communications signal that is transmitted over a communication channel. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
