CALIBRATING RECONSTRUCTED SIGNAL USING MULTI-TONE CALIBRATION SIGNAL |
摘要 |
A method of calibrating a reconstructed signal from a plurality of sub-signals is provided. The method includes injecting a calibration signal having multiple tones into a received input signal; dividing the input signal into a first and second sub-signal, including an overlapping frequency band; performing a first frequency translation by converting frequency components of the second sub-signal; digitizing the first sub-signal and the frequency converted second sub-signal; performing a second frequency translation to reverse the first frequency translation to obtain a reconstructed second sub-signal; and quantifying impairments to the digital first sub-signal and reconstructed second sub-signal caused by differences in magnitude and phase of frequency components within the overlapping frequency band.
