Abstract
Systems and techniques relating to wireless communications are described. A described technique includes generating a digital transmit signal, receiving a digital receive signal, storing signal samples, the signal samples including transmit samples based on the digital transmit signal and receive samples based on the digital receive signal, causing, in a predistortion training mode, the digital receive signal to be based on an amplified analog version of the digital transmit signal, where the amplified analog version is produced by a power amplifier having one or more nonlinear characteristics, determining a synchronization offset value to align the transmit samples with the receive samples, determining one or more power normalization parameter values to normalize a power of the digital receive signal with respect to the digital transmit signal, estimating predistortion parameter values, and using the predistortion parameter values to predistort digital signals to compensate for the one or more nonlinear characteristics of the power amplifier. Estimating predistortion parameter values can include using information comprising the transmit samples, the receive samples, the synchronization offset value, and the one or more power normalization parameter values.
