SYSTEM AND METHOD OF MULTI-USER MULTIPLE TRANSMITTING AND RECEIVING ANTENNA COMMUNICATIONS

摘要

A multi-user multi-transceiving antenna system and a method are provided to enable plural receivers to generate feedback information by extracting channel states of grouped antennas connected with a transmitter and to send the generated information, thereby decreasing feedback capacities. When plural pilot signals are received from a transmitter(100), a receiver(200) generates feedback information by measuring quality of channels through which the plural pilot signals are transmitted, and transmits the generated feedback information to the transmitter(100). When the generated feedback information is received, the transmitter(100) analyzes the received feedback information to schedule streams transmitted to the receiver(200). The transmitter(100) consists of a controller(110), a feedback information processor(140), a coding and modulating unit(120) and a multi-outputting unit(130), and the receivers(200) comprises a quality measuring unit(210), a detecting unit(220), a multi-receiving unit(230) and a decoding modulator(240).
