摘要： A transmission apparatus and method include modulating a transmission signal using a first modulation scheme selected from a plurality of modulation schemes to generate a first symbol sequence. A second symbol, generated using a phase shift keying (PSK) modulation scheme, is inserted in the first symbol sequence to generate a first modulation signal for transmission. A second modulation signal is received that includes a third symbol generated using a PSK modulation scheme and inserted in a second symbol sequence generated using a second modulation scheme selected from the plurality of modulation schemes. The third symbol is extracted from the received modulation signal. A transmission path associated with the received modulation signal is estimated using the third symbol. A received data signal from the second symbol sequence included in the received modulation signal is output using the estimated transmission path.

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 radio communication apparatus includes a QPSK modulator that modulates transmission data to produce a QPSK modulation signal and a 64QAM modulator that modulates transmission data to produce a 64QAM modulation signal. A radio transmitter receives the QPSK modulation signal and the 64QAM modulation signal and outputs a transmission signal. An average transmission power of the QPSK modulation signal and the 64QAM modulation signal are within a predetermined output power range.
