HPLC dual-mode communication carrier signal enhancement technology under strong electromagnetic interference

Strong electromagnetic interference caused by lightning or large electronic devices inundates the HPLC dualmode communication carrier signal, resulting in a lot of chaotic signals, poor signal-to-noise ratio, and easy interruption. In order to improve the anti-interference ability of dual-mode communication systems under strong electromagnetic interference, this paper proposes HPLC dual-mode communication carrier signal enhancement technology under strong electromagnetic interference. Extract the characteristics of the HPLC dual-mode communication carrier signal and encode the strong electromagnetic interference of the HPLC dual-mode communication carrier signal. Using empirical mode decomposition algorithm to decompose the carrier signal, and using wavelet transform decomposition algorithm to filter and suppress interference, to achieve HPLC dual-mode communication carrier signal enhancement. The experimental results show that this method can effectively remove cluttered signals and significantly reduce the frequency of signal fluctuations. After adding strong electromagnetic waves, the signal fluctuates greatly and the signal-to-noise ratio is low. After the proposed method, the signal-to-noise ratio of the HPLC dualmode communication carrier signal was improved to over 35dB, and the fluctuations were relatively smooth. This method effectively removes interference and improves the signal enhancement effect.
