摘要：
The high peak-to-average power ratio (PAR) in real-baseband discrete multitone modulation (DMT) systems can significantly limit performance. Tone reservation techniques use unavailable or reserved tones to design a peak-cancelling signal that lowers the PAR of a transmit data block. Previous methods converge very slowly to a good solution. Our new active-set method converges much faster toward a minimum-PAR solution at a lower cost.
