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.
