Abstract: The present disclosure includes systems and techniques relating to calibrating I/Q mismatches in communication systems. In some implementations, a reference signal to be transmitted by a transmitter (Tx) is identified. A loopback signal corresponding to the reference signal is generated by passing the reference signal through the TX and a receiver (Rx). The loopback signal includes an additional signal that distinguishes an in-phase/quadrature (I/Q) mismatch caused by the Tx (Tx I/Q mismatch) from an I/Q mismatch caused by the Rx (RX I/Q mismatch). A set of Tx I/Q mismatch parameters and a set of Rx I/Q mismatch parameters are determined based on the reference signal and the loopback signal, using the additional signal. A Tx signal is calibrated based on the set of Tx I/Q mismatch parameters, while a Rx signal is calibrated based on the set of Rx I/Q mismatch parameters, independently from the calibrating the Tx signal.

Abstract: An apparatus comprises an amplifier and a pre-distortion circuit coupled to an input of the amplifier. A saturation value of an input signal corresponds to a maximum output power of an output signal of the amplifier. An input target value of the input signal is determined according to the saturation value. The input target value is determined by subtracting an offset from the saturation value or by multiplying a ratio by the saturation value. An average value or an RMS value of the input signal is controlled to be substantially equal to the input target value. A method comprises determining an input target value according to a saturation value, and controlling an input signal according to the input target value.
