1. A system for receiving magnetic resonance signals, the system comprising:

  • a receiving coil array comprising at least one coil unit group;

    a correlation recording unit configured to record correlations between carrier frequencies and signals received by each coil unit in a corresponding coil unit group of the at least one coil unit group;

    a low noise amplification, filtering and frequency mixing unit configured to perform frequency mixing on anti-aliasing filtered signals according to the correlations recorded by the correlation recording unit after performing low noise amplification and anti-aliasing filtering on the signals received by the coil units in the at least one coil unit group to obtain intermediate frequency signals borne on the respectively corresponding carrier frequencies of an identical channel;

    an amplification and filtering unit configured to perform amplification and filtering processing on the intermediate frequency signals; and

    an analog-to-digital conversion unit configured to perform digital sampling on the signals processed by the amplification and filtering unit to obtain digital domain signals.
