Transmitter and receiver for high throughput wireless communication system using multiple antenna, method thereof, and digital intermediate frequency transmission signal processing method for the same

A receiver for a high throughput wireless communication system using a multiple antenna, comprising:

• a Radio Frequency (RF) receiving means for down-converting and outputting each RF signal received through the multiple antenna;
• a digital intermediate frequency (DIF) receiving means for dividing and outputting m channel signals received from the RF receiving means where m is a predetermined natural number into n band signals where n is a predetermined natural number;
• and
• a baseband receiving means for receiving signals of each band divided in the DIF receiving means and recovering data through a physical layer process, multiple signal detection and channel decoding.

A method for transmitting data in a high throughput wireless communication system using a multiple antenna, comprising:

• processing a signal by performing a Media Access Control (MAC) protocol process on transmission data and dividing data into n band signals where n is a predetermined natural number in a physical layer process;
• integrating and outputting the divided and processed transmission signals as m channel signals where m is a predetermined natural number;
• and
• modulating each channel signal into an RF signal and emitting the signal through the multiple antenna.
