摘要: A method for I/Q mismatch calibration of a receiver having an correction module with parameters, comprising the steps generating test signal containing single tone waveform frequency carrier plus predetermined frequency, applying demodulation to reduce central and outputting demodulated signal, converting digital obtaining measures respectively indicative response at minus frequencies, calculating set parameters based on measures.
