Abstract
Systems and techniques relating to wireless communications are described. A described technique includes operating a device, that includes a receive filter, in different modes comprising an operational mode and a predistortion training mode, where the receive filter is configured to operate at a first bandwidth during the operational mode and operate at a second, wider bandwidth during the predistortion training mode; generating a digital transmit signal; receiving a digital receive signal via the receive filter, causing, in the predistortion training mode, the digital receive signal to be based on an amplified analog version of the digital transmit signal, the amplified analog version being produced by a power amplifier having a nonlinear characteristic(s); estimating predistortion parameter value(s) using samples of the digital transmit signal and samples of the digital receive signal; and using the predistortion parameter value(s) to predistort digital signals to compensate for the nonlinear characteristic(s) of the power amplifier.
