APPARATUS, METHOD AND SUBCARRIER STRUCTURE FOR TRANSMITTING AND RECEIVING IN MULTIUSER MULTIPLE ANTENNA COMMUNICATION SYSTEMS

摘要

The present invention relates to a transmitter or receiver and the transmitter or receiving method of the multi-antenna communication system, especially the transmitter It calculates a reception filter for each receiver antenna, or a plurality of individual receivers in and to choose a previously known that the best correlation with the receive filter vector calculated by the code book index of the vector to establish the reception filter index, receiving the transmitter and a transmission method and the receiving filter index which transmits it to the receiver, to a receiver and receiving method using a vector corresponding to the index in the code book in the receiving filter previously known to the receiving filter.
