To achieve the optimal power control of a system in an MIMO communication method. When decoding in accordance with a receiving algorithm of the MIMO communication method in plural receivers, each receiver acquires the reception power level of a received signal from a transmitter paired with the receiver, and generates a transmitter power control signal based on a comparison result of comparing the reception power with a predetermined value. For example, if the reception power level is lower than the predetermined value, a transmitter power control signal of instructing to increase the transmitter power is generated, or otherwise, a transmitter power control signal of instructing to decrease the transmitter power is generated. The generated control signal is transmitted from the receiver to the transmitter paired with the receiver. Each transmitter controls the transmitter power in accordance with the received control signal. |
