摘要： A transceiver device that performs an intercept point calibration using signal interferers is described. The signal interferers include at least self-generated signal interferers or opportunistic signal interferers in surrounding areas. Due to non-linearity in the transceiver device, intermodulation distortion (IMD) signal components are generated. Filtering of the IMD signal components is performed to allow low-frequency components, such as a second order intermodulation (IM2) to pass through. A dynamic minimization algorithm is performed to minimize distortion effects of the low-frequency components.
