Abstract
Disclosed in the present invention are a data transmission method, an apparatus and an antenna array, in order to realize wide bandwidth data transmission of massive antenna array. The data transmission method comprises: baseband IQ data of multiple CA is grouped via IR data interface module to obtain baseband IQ data of each CA group; for baseband IQ data of each CA group: the baseband IQ data with enhanced data rate of the CA group is up-converted to digital intermediate frequency band by a digital up-conversion module; the digital intermediate frequency signals of the CA group are superposed by a combiner to form a multi-carrier digital intermediate frequency signal; in accordance with the amplitude and phase requirements of each antenna in a group of antenna sharing the multi-carrier digital intermediate frequency signal, the amplitude and phase of the multi-carrier digital intermediate frequency signal are respectively adjusted and transmitted to a digital to analog converter of a corresponding antenna channel; a multi-carrier analog intermediate frequency signal is generated by the digital to analog converter of each antenna channel, and then is transmitted to the correspondi…
