Patent ID: 8422465

Claim:
A transmitter for a high throughput wireless communication system using multiple antennas, comprising: a baseband transmitting means for processing a transmission signal by performing a Media Access Control (MAC) protocol process on transmission data and dividing the transmission data into n band signals where n is a predetermined natural number greater than one in a physical layer process, each of the n band signals having a bandwidth of a predetermined bandwidth unit and the transmission data having a bandwidth of n multiples of the predetermined bandwidth unit; a digital intermediate frequency (DIF) transmitting means for integrating each of the n band signals transmitted from the baseband transmitting means and outputting m channel signals where m is a predetermined natural number greater than one, each one of the m channel signals being generated by integrating every one of the n band signals and converting to an analog signal of an intermediate frequency (IF); and a Radio Frequency (RF) transmitting means for modulating each of the m channel signals transmitted from the DIF transmitting means into an RF signal and emitting the RF signal through a corresponding one of m antennas.
