APPARATUS AND METHOD OF TRANSMITTING DATA USING MULTIPLE ANTENNA

摘要

PURPOSE: A device and a method for transmitting data using multiple antenna using are provided to transmit data which has different attributes to each other through multi antenna, thereby expanding a coverage. CONSTITUTION: A demultiplexer(110) divides the first type data to a plurality of sub data. The pre-coder(120) maps a plurality of sub data to a plurality of antennas by granting the first weight about a plurality of sub data. The second pre-coder maps the second type data to a plurality of antenna by granting the second weight about the second type data. A transmission processor(140) transmits the firs type data with the second type data through a plurality of antenna.
