Abstract

The present invention relates to transmitting/receiving apparatuses of a wideband radio channel measuring device using a multi-carrier. The wideband radio channel measuring device using the multi-carrier may measure radio channel characteristics at a frequency domain. Since the radio channel is measured at the frequency domain by the wideband radio channel measuring device using the multi-carrier, the channel characteristics may be simultaneously measured while maintaining a maximum Doppler measurement frequency at a predetermined level regardless of increase of the number of transmitting and receiving antennas, in an MIMO configuration.
