Patent ID: 8396102

Claim:
A transmitting apparatus of a high-throughput wireless communication system using multiple antennas, the transmitting apparatus comprising: a baseband transmitter configured to perform a medium access control (MAC) protocol process on transmission signals and reception signals and process the transmission signals by dividing an entire transmission band into n bands in a physical layer process of transmission data, where n is a natural number; a digital intermediate frequency (DIF) transmitter configured to combine the transmission signals of n bands from the baseband transmitter and output m channel signals corresponding to a number of transmission antennas, where m is a natural number; and a radio frequency (RF) transmitter configured to modulate each of the m channel signals transferred from the DIF transmitter and transmit the modulated signals through m transmission antennas, wherein the baseband transmitter includes: a receiving buffer configured to temporarily store received data; a medium access control (MAC) processor configured to transfer the buffered data from the receiving buffer to an external device through an Ethernet interface by processing the buffered data through the MAC protocol process; a plurality of physical layer processers configured to perform the physical layer process by dividing transmission packet data transferred from the MAC processor by a predetermined band; and a plurality of first super high speed transmitting units corresponding to the plurality of physical layer processors in a one-to-one manner and configured to transfer the transmission signals of each band to the DIF transmitter.
