System and method for transmitting highly correlated preambles in QAM constellations

摘要

A method for transmitting a data signal where the data signal includes a preamble portion preceding a payload portion that reduces harmonic spikes is presented. The method reduces the transmission power for portions of bursty data signal that contain highly correlated or repetitive preamble sequences relative to the transmission power that contain non-highly correlated or repetitive payload sequences. The resultant average output power of the preamble sequences is approximately equal to the average output power of the payload sequences.
