1. A method for transmitting data, the method comprising:

  • dividing, by an interface radio frequency (IR) data interface module, baseband in-phase and quadrature (IQ) data of multiple carrier antennas (CAs) into groups to obtain baseband IQ data of each group of CAs; and

    for the baseband IQ data of each group of CAs;

    increasing, by an interpolation and filter module, a data rate of the baseband IQ data of the group of CAs;

    up-converting, by a digital up-conversion module, the baseband IQ data of the group of CAs having the increased data rate into a digital intermediate-frequency band to obtain digital intermediate-frequency signals of the group of CAs;

    adding, by a combiner, the digital intermediate-frequency signals of the group of CAs together to form a multi-carrier digital intermediate-frequency signal;

    adjusting, by an amplitude and phase adjustment module, an amplitude and a phase of the multi-carrier digital intermediate-frequency signal as required by each antenna in a group of antennas sharing the multi-carrier digital intermediate-frequency signal, respectively, and then transmitting the adjusted multi-carrier digital intermediate-frequency signals to digital to analog converters of corresponding antenna channels; and

    generating, by the digital to analog converters of the corresponding antenna channels, multi-carrier analog intermediate-frequency signals, and transmitting the multi-carrier analog intermediate-frequency signals to the corresponding antenna channels.
