APPARATUS AND METHOD FOR TRANSMITTING DATA USING MULTIPLE ANTENNAS |
摘要 |
A data transmission apparatus having a plurality of antennas in a frequency division multiplexing system is provided. The apparatus includes a demultiplexer for splitting first-type data into plural pieces of sub-data, a first precoder for mapping the plural pieces of sub-data to the plurality of antennas by applying a first weight, a second precoder for mapping second-type data with an attribute different from the first-type data to the plurality of antennas by applying a second weight, and a transmit processor for transmitting the first-type data together with the second-type data through the plurality of antennas. Coverage can be expanded, and different types of services can be concurrently provided and system management can be achieved with increased flexibility and reliability. |
