Method of ip2 calibration for wireless transceiver and device for performing ip2 calibration

A second order intercept point (IP2) calibration method for a wireless transceiver, the IP2 calibration method comprising:

• determining an I-start correction code and a Q-start correction code based on an calculation method based on at least one of a fixed in-phase correction code (I-correction code) or a fixed quadrature-phase correction code (Q-correction code);
• determining an I-intermediate correction code and a Q-intermediate correction code based on a binary search method based on the I-start correction code and the Q-start correction code;
• and
• determining an I-final correction code and a Q-final correction code based on a plurality of points comprising a point composed of the I-intermediate correction code and the Q-intermediate correction code.

A device configured to perform second order intercept point (IP2) calibration for a wireless transceiver, the device comprising:

• a memory storing instructions;
• an interface configured to:
• receive, from the wireless transceiver, a signal comprising second order intermodulation distortion (IMD2);
• and
• transmit, to the wireless transceiver, an in-phase correction code (I-correction code) and a quadrature-phase correction code (Q-correction code);
• and
• a neural network processor communicatively coupled to the interface and to the memory, wherein the neural network processor is configured to:
• set parameters of a plurality of heterogeneous methods based on a plurality of pieces of IP2 calibration data collected from the interface;
• and
• determine an I-final correction code and a Q-final correction code that minimizes the IMD2 based on the plurality of heterogeneous methods.
