Embodiment 1
[0049] This embodiment proposes a nonlinear correction method and device for improving the spurious-free dynamic range of an analog-to-digital converter.
[0050] Such as figure 1 As shown, the nonlinear correction device of this embodiment includes a training signal generation module, a network parameter detection and extraction unit, an analog-to-digital converter, and a nonlinear correction processing unit.
[0051] The working principle of the non-linear correction method and device of the present embodiment is as follows:
[0052] In this embodiment, the correction of nonlinear distortion is realized by using the source equivalent network parameter data, specifically as follows: firstly, the network parameter detection and extraction unit obtains the training signal and extracts the source equivalent network parameter data of the training signal, and the source of the training signal The equivalent network parameter data is transmitted to the nonlinear correction process...
Embodiment 2
[0069] In this embodiment, the nonlinear correction method and device proposed in the above-mentioned embodiment 1 are used to correct the single-tone signal, the dual-tone signal and the actual analog input signal, and respectively obtain FFT frequency diagrams before and after correction.
[0070] Such as figure 2 As shown, the measured FFT spectrograms before and after the single-tone signal is corrected using the nonlinear correction method and device proposed in the above-mentioned embodiment 1 are shown by figure 2 It can be seen that the single-tone spurious-free dynamic range of the analog-to-digital converter is increased by 41 dB by using the nonlinear correction of the present invention.
[0071] Such as image 3 As shown, the measured FFT spectrograms before and after the two-tone signal is corrected by using the nonlinear correction method and device proposed in the above-mentioned embodiment 1 are shown by image 3 It can be known that the dual-tone spurious-...
