Abstract:
A system and method for communicating includes a transmitter that transmits a communication signal having a plurality of successive frames, with each frame formed with alternatively arranged N known data symbols and M unknown data symbols such that the N known data symbols as training symbols. The communications signals are received within a receiver. The N known data symbols are synchronized at the receiver by correlating and time averaging the N known data symbols.
