New Techniques for Multicarrier Communication Systems
… that lowers the PAR of a transmit OFDM block. Active-set methods provide a fast-converging PAR reduction technique that can be applied to real- and complex-baseband OFDM systems. In systems where data tones cannot be sacrificed, PAR reduction can be obtained using active (data-carrying) …

Fast peak-power reduction for MIMO-OFDM systems with diversity
A robust peak-power reduction technique called active constellation extension (ACE) reduces the peak-to-average power ratio (PAPR) of single-input single-output (SISO) orthogonal frequency-division modulated (OFDM) signals by extending the outer constellation points in a way that minimizes the PAPR …
