A mobile platform apparatus for a multiple antenna system and an apparatus for verifying the mobile platform apparatus are provided. The mobile platform apparatus includes: a baseband unit which receives transmission data to be transmitted to the external system, modulates the transmission data, receives baseband reception data, and demodulates the baseband reception data; an intermediate frequency (IF) unit which receives the modulated transmission data from the baseband unit, converts the modulated transmission data into IF transmission data, receives IF reception data, converts the IF reception data into the baseband reception data, and transmits the baseband reception data to the baseband unit; and a radio frequency (RF) unit which receives the IF transmission data from the IF unit, converts the IF transmission data into RF transmission data, transmits the RF transmission data to the external system, receives RF reception data from the external system, converts the RF reception data into the IF reception data, and transmits the IF reception data to the IF unit. Each of the IF unit and the RF unit comprises a plurality of paths, and the transmission data and the reception data are transmitted via at least one of the paths. Therefore, it is possible to provide a terminal function which can be executed either in real time mode or in non-real time mode in a multi-band multi-carrier environment for fourth generation wireless communication systems.
