  • Data transmission method using dirty paper coding in mimo system
    Publication number: 20090274235
    Abstract: A data transmission method for multiple users having multiple receive antennas is provided. The method includes selecting a receive antenna among the multiple receive antennas for each user, performing DPC (Dirty Paper Coding) from the multiple transmit antennas to the receive antenna and transmitting a transmission signal on which the DPC is performed. Since DPC is implemented through a receive antenna selected among multiple receive antennas, complexity is not much increased although the DPC is applied to a MIMO system.
