Abstract
Disclosed herein is an apparatus and methodology for reducing peak-to-average-power ratio (PAPR) for IQ radio frequency digital-to-analog converter (RFDAC). Processing circuitry may be configured to generate a digital signal comprising an in-phase (I) signal component and a quadrature (Q) signal component having a peak-to-average-power-ratio (PAPR). The processing circuitry may determine the I signal component and the Q signal component are higher than a predetermined threshold value, and limit the I signal component and the Q signal component to be less than or equal to the predetermined threshold value. The processing circuitry may rotate the signal components to generate rotated signal components to reduce the PAPR based on the I and Q signal components having less than or equal to the predetermined threshold value, and may generate an output radio frequency (RF) signal based on the rotated signal components.
