PEAK-TO-AVERAGE POWER RATIO REDUCTION WITH BOUNDED ERROR VECTOR MAGNITUDE

摘要

Method and apparatus for signal processing to minimize the peak to average power ratio of an Orthogonal Frequency Division Multiplexing ("OFDM") or Orthogonal Frequency Division Multiple Access ("OFDMA") signal with bounded error vector magnitude for an integrated circuit (100) are described. An Active Constellation Extension ("ACE") iteration is performed. Symbols outside of a bounded region (520, 620) after the ACE iteration are identified. The bounded region (520, 620) is determined responsive to an error vector magnitude target. The symbols identified are translated to the bounded region (520, 620).
