Abstract
A MIMO transceiver may include a communication chain configured to generate a signal at a first frequency and that includes a pre-distorter configured to accept pre-distortion parameters to pre-distort signals and a PA to amplify the signals. The MIMO transceiver may include a DPD chain configured to receive the signal at the first frequency and that includes a data converter to sample the signal using a sampling rate based on a baseband frequency and to generate a sample signal based on the sampling of the signal. The MIMO transceiver may include a buffer configured to buffer the sample signal. The MIMO transceiver may include a DPD circuit configured to calibrate the pre-distortion parameters based on the buffered sample signal. The MIMO transceiver may include a CTS circuit to transmit a CTS-to-Self signal within an operational environment to reserve a duration of time for the MIMO transceiver to perform DPD calibration.
