APPARATUS FOR TRANSMITTING DATA BY THE USAGE OF THE PRECODING MATRICES AFTER GENERATING PRECODING MATRIX BASED CHANNEL STATE INFORMATION

摘要

PURPOSE: An apparatus for transmitting data by the usage of the precoding matrices after generating precoding matrix based channel state information is provided to determine precoding matrix according to the quantization noise.;CONSTITUTION: A receiver(310) receives status information which is quantized about a radio channel from a plurality of transmission antenna(361) of the base station to a plurality of RX-antennas(381) of a termina from the terminal. A controller decides the controlled rate of the interference signal to noise about the radio channel. A precoding matrix calculator produces the precoding matrices. Using the usage of the precoding matrices, a transmission unit transmits data to each terminal.;COPYRIGHT KIPO 2010
