Abstract
Systems, methods, and devices are provided for correcting compression distortion of wireless signals due to variations in operation parameters of the radio frequency system. The method may include using circuitry to generate a reference signal that is not pre-distorted by a processing block. The method may involve receiving an envelope signal representative of a signal being transmitted by a transceiver. The method may also involve determining a first peak-to-average ratio of the envelope signal and receiving a second peak-to-average ratio of the reference signal. The method may additionally involve determining a difference between the first peak-to-average ratio and the second peak-to-average ratio. The method may also include adjusting a gain of an amplifier of the transceiver based on the difference.
