description The embodiment of the invention provides an IQ imbalance calibration method, electronic equipment and a storage medium, the random access method is applied to a wireless transceiver component, and comprises the following steps: generating a first single-tone signal, converting the first single-tone signal into a first radio frequency single-tone signal, and transmitting the first radio frequency single-tone signal; acquiring first baseband data transmitted by the I receiving path and second baseband data transmitted by the Q receiving path; calculating a gain mismatch calibration coefficient and a phase mismatch calibration coefficient according to the first baseband data and the second baseband data; and compensating the baseband signal of the I receiving path and/or the baseband signal of the Q receiving path according to the gain mismatch calibration coefficient and the phase mismatch calibration coefficient. According to the IQ imbalance calibration method provided by the invention, self-calibration can b
