Abstract
A MIMO transceiver configured for digital pre-distortion may include a first communication chain configured to wirelessly transmit a signal at a first frequency. The first communication chain may include a pre-distorter circuit configured to accept parameters to pre-distort signals prior to transmission. The first communication chain may include a PA configured to amplify the signals of the first communication chain prior to transmission. The MIMO transceiver may include a second communication chain. The second communication chain may be configured to wirelessly receive the signal at the first frequency. The second communication chain may include a converter circuit configured to convert the signal to a baseband frequency. The second communication chain may include a buffer configured to buffer the signal at the baseband frequency. The MIMO transceiver may include a DPD circuit configured to calibrate the parameters based on the buffered signal to compensate for non-linearity in amplification by the PA.
