Abstract: In an example embodiment, a full duplex transceiver includes an analog-to-digital converter (ADC), at least one processor, a first digital-to-analog converter (DAC) and an amplifier. The ADC is configured to convert an analog first signal to a digital first signal, the analog first signal being based on a transmitted signal from the transceiver and a received signal from a far-end transceiver. The at least one processor is configured to determine pre-distortion compensation coefficients using the digital first signal and a first input signal and generate a pre-distorted compensated input signal based on the pre-distortion compensation coefficients. The first DAC is configured to convert the pre-distortion compensated input signal to an analog input signal. The amplifier is configured to amplify the analog input signal to a subsequent transmit signal.
