Abstract: A signal transmitting method suitable for a MU-MIMO environment and achieving a high performance with low complexity is provided. The signal transmitting method includes: splitting each message stream into a common message stream and a private message stream; combining a plurality of common message streams for the plurality of receivers to generate a common stream; encoding the common stream and private message streams for the plurality of receivers to generate an encoded common stream and encoded private message streams; precoding the encoded common stream and the encoded private message streams to adjust amplitudes and phases of symbols such that power is distributed between the encoded common stream and the encoded private message streams and generate precoded signals; and converting the precoded signals into a plurality of RF signals, adjusting phases of the plurality of RF signals, and outputting the phase-adjusted RF signals through a plurality of MIMO antennas.
