Method and apparatus for spatial multiplexing transmission

摘要

The present invention relates to a method and apparatus for spatial multiplexing transmission using multiple antennas. The method for spatial multiplexing transmission includes the steps of: assigning different transmission power weights to sequentially transmitted signals in a cross-coupled fashion; precoding the sequentially transmitted signals assigned with the transmission power weights; converting the precoded sequentially transmitted signals into parallel transmitted signals; inputting, in a cross-coupled fashion, the parallel transmitted signals into a first amplifier connected to a first antenna constituting the multiple antennas and a second amplifier connected to a second antenna constituting the multiple antennas. According to the present invention, the reception range for a signal to be transmitted to each antenna constituting the multiple antennas can be adjusted to be equal.
