Abstract: Provided is control information related to polarizations of antennas for MISO communication. The control signal generator generates polarization information indicating whether antennas used for transmission by MISO have only a first polarization or have a second polarization as well as the first polarization. With this structure, the present invention allows for the use of combinations of SISO, MISO and MIMO, taking the polarization of antennas. Furthermore, the present invention enables the receiver to reduce the power consumption.

Abstract: In a transmission method according to one aspect of the present disclosure, quality of received data can be improved in a reception device, when a probability of increasing a minimum Euclid at a signal point in an in-phase I-orthogonal Q plane during reception is increased in a radio wave propagation environment in which a direct wave is dominant. This enables provision of an MIMO (Multiple-Input Multiple-Output) system, which can improve the reception quality in an LOS environment while a plurality of transmit antennas and a plurality of receive antennas are used.

Abstract: Disclosed is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals that are transmitted in the same frequency bandwidth at the same time. According to the precoding method, one matrix is selected from among matrices defining a precoding process that is performed on the plurality of baseband signals by hopping between the matrices. A first baseband signal and a second baseband signal relating to a first coded block and a second coded block generated by using a predetermined error correction block coding scheme satisfy a given condition.

Abstract: An indicator in a master AP from among a plurality of APs obtains communication quality of communication with an AP which is a communication partner. In the case where the obtained communication quality is less than a threshold, the indicator causes the plurality of APs including the master AP to perform cooperative operation to transmit data. In the case where the obtained communication quality is not less than the threshold, the indicator causes the plurality of APs including the master AP to stop the cooperative operation.

Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s 1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.

Abstract: A transmission method of simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals. One of signal generation processing in which phase change is performed and signal generation processing in which phase change is not performed is selectable, thereby improving general versatility in signal generation.
