    摘要: The present method groups a transmission data stream, taking a combination of data bits to be transmitted from a part or all of the plurality of transmission antennas at the same time as one group; and performs transmission processing, including at least either of bit repetition processing or retransmission processing by the unit of the group (bit combination). As a result, in MIMO communication, etc., it is possible to suppress deterioration of reception characteristic due to vanishing of correlation among bits transmitted at the same time.

    摘要: A first adjustment circuit adjusts an impedance of a first antenna, and a second adjustment circuit adjusts an impedance of a second antenna. A coupling reduction circuit reduces an amount of coupling of the first and second antennas. A first reception power measurement unit measures first reception power received from the first antenna, and a second reception power measurement unit measures second reception power received from the second antenna. A selection unit selects a circuit from among the first adjustment circuit, the second adjustment circuit, and the coupling reduction circuit. A circuit control unit controls the impedance of the selected circuit so that the value of the evaluation function proportional to the product of the first reception power and the second reception power becomes larger.
