Abstract

A frequency division duplex communications transceiver is provided having an adaptive pre-distortion circuit for linearising a powered amplifier of the transceiver. The feedback path used for the pre-distortion circuit and the receiver path are combined and simultaneously digitised by single analogue to digital converter. By combining the feedback signal and the received signal in this way, the circuit complexity is reduced which in turn reduces the cost of the transceiver circuit.
