METHOD FOR TRANSMITTING DATA IN MULTIPLE ANTENNA SYSTEM

摘要

PURPOSE: A method for transmitting data in a multiple antenna system is provided to reduce the complexity of system by utilizing an existing code book for the multiple antennas. CONSTITUTION: A first antenna cluster and a second antenna cluster are composed. A channel subordinate pre-coding is applied to the antenna cluster and the second antenna cluster. A transmission signal is generated. The channel subordinate pre-coding is operated by a pre-coding weight matrix. The pre-coding weighted value is expressed in the PxV for a hierarchy number(V) and transmission antenna number(P). The P and V are fixed numbers greater than 0. The transmission signal is transmitted.
