A radio with a system for cancelation of noise, distortion, and interference products is calibrated using a test signal. The test signal is inserted in a radio transmit path, amplified, and down-converted. The test signal may be converted from the digital domain prior to amplification, and up-converted prior to amplification. The down-converted amplified test signal is compared with a signal in the receive path, to measure test signal distortion in the receive path. A distortion model is calibrated based on the test signal, and parameters of the distortion model may be stored. |
