Abstract: A method for determining a transmission power in a multi-input multi-output (MIMO) system based on a cooperative transmission is provided. The method includes setting a power constraint condition of a transmitter and target quality information of a receiver. The method further includes determining the transmission power to be allocated to the transmitter to transmit the data to the receiver based on the power constraint condition and the target quality information.

Abstract: A transmitter configured to support a multimode and a multiband, using radio frequency (RF) digital-to-analog converters (DACs), includes a first RF DAC configured to transmit a first signal in a first frequency band, and a second RF DAC configured to transmit a second signal in a second frequency band different from the first frequency band. The transmitter further includes an impedance controller configured to adjust impedance of one of the first RF DAC and the second RF DAC operating in an impedance matching mode to adjust a frequency range of another one of the first RF DAC and the second RF DAC operating in a data transmission mode.
