Zusammenfassung:	PURPOSE: A space multiplexing transmission method and a device thereof are provided to equally control the reception range of a signal transmitted to each antenna. CONSTITUTION: R signals passed through a serial-parallel converter(410) are alternatively inputted to amplifiers(420,430) in every input time The signals are transmitted through antennas(440,450). R signals are inputted as an input signal to an amplifier connected to a first antenna, wherein the r signals are precoded with a transmission signal x to which a transmission power weight is alternatively applied. R signals are inputted as an input signal to an amplifier connected to a second antenna, wherein the r signals are precoded with a transmission signal x to which a transmission power weight is alternatively applied.
