    摘要： A transmission apparatus maps a first stream of input data to first complex symbols in serial format and convert them into first complex symbols in parallel format. They are inverse Fourier transformed into OFDM signals associated with multiple subcarriers that are transmitted via a first antenna over the multiple subcarriers in a same frequency band over a same time period that includes a same set of time slots. First pilot information is transmitted via a first antenna on a first one of a plurality of pilot subcarriers during the same set of time slots, and second pilot information is sent via a first antenna on a second one of a plurality of pilot subcarriers during the same set of time slots. The second pilot information is different from the first pilot information. A second stream of input data is similarly transformed to form second OFDM signals transmit via a second antenna over the multiple subcarriers in the same frequency band over the same time period that includes the same set of time slots. The first pilot information is transmitted via the second antenna on the second pilot subcarrier during the set of same time slots, and the second pilot information is transmitted on one of the pilot subcarriers during the same set of time slots.

    摘要： A transmission apparatus includes processing circuitry that generates a first data sequence representing first data or a second data sequence representing second data different from the first data and selects the first data sequence as an output data sequence. A modulation scheme is determined from a plurality of modulation schemes, and the output data sequence is modulated with the determined modulation scheme. Transmission circuitry transmits the modulated output data sequence. A first time interval associated with selecting the first data sequence for the output data sequence is longer than a second time interval associated with determining the determined modulation scheme.

    摘要： A transmission apparatus includes a plurality of antennas and a transmission scheme determination processor that selects one of either a first transmission scheme of transmitting a plurality of signals including a first amount of data in a frame, respectively, from the plurality of antennas, and a second transmission scheme of transmitting a plurality of signals including a second greater amount of data in a frame, respectively, from the plurality of antennas. The apparatus includes a modulation scheme selection processor that selects a modulation scheme among a plurality of modulation schemes and a control processor that controls the transmission scheme determination processor and the modulation scheme selection processor to change the transmission scheme less frequently than the modulation scheme. A transmitter transmits from the plurality of antennas a signal generated based on the selected transmission scheme and the selected modulation scheme.

    摘要： A radio transmission apparatus determines information indicative of an estimated communications channel condition and generates a single modulation signal or a plurality of modulation signals based on the estimated communications channel condition information. The single modulation signal from a first antenna or the plurality of modulation signals is(are) transmitted from the first antenna and a second antenna. The plurality of modulation signals include different information from each other and are transmitted over an identical frequency band and at an identical temporal point. The single modulation signal and the plurality of modulation signals contain parameter information indicating a number of modulation signals transmitted at the same time.
