Abstract
Embodiments of apparatus and method for calibration of a transceiver (including a transmitter and a receiver) are disclosed. In an example, a method for transmitter quadrature (or IQ) mismatch and receiver quadrature (or IQ) mismatch calibration can include controlling the transmitter to send a first transmit signal to the receiver with a delay between an output of the transmitter and an input of the receiver. The method can also include controlling the transmitter to send a second transmit signal to the receiver without the delay between the output of the transmitter and the input of the receiver. The method can further include obtaining compensation coefficients of the transceiver based on the sending of the first transmit signal and the sending of the second transmit signal.
