    摘要: SP signals to be transmitted from a first transmitting antenna 11 are arranged in the same pattern as SP signals to be transmitted from a second transmitting antenna 12. The SP signals to be transmitted from the second transmitting antenna 12 in one symbol are generated, such that the polarity of the SP signals are alternately inverted and non-inverted with respect to the SP signals to be transmitted from the first transmitting antenna 11 in the same symbol. Thus, in the direction that the symbol number is incremented by 1 and the carrier number is incremented by 3, the polarity of SP signals transmitted from the second transmitting antenna 12 are all inverted or non-inverted with respect to the polarity of corresponding SP signals transmitted from the first transmitting antenna 11.

    摘要: A digital broadcast transmission device generates channel combination information associating a plurality of physical channels. The digital broadcast transmission device divides a bit stream into a plurality of bit streams, the bit stream including program-related information having added thereto channel combination information, and transmits the divided bit streams on the plurality of physical channels, respectively. A digital broadcast reception device selects the plurality of physical channels using a plurality of front ends based on the channel combination information, and demodulates broadcast waves received on the plurality of physical channels, respectively. The digital broadcast reception device combines bit streams obtained from the demodulation, and outputs the combined bit stream. The digital broadcast reception device also simultaneously transmits a light bit stream on a different single physical channel, the light bit stream being a bit stream smaller in amount of information than the combined bit stream.

    摘要: An object is to generate a pilot signal for estimating transmission characteristic of a transmission channel which is suitable for the OFDM/OQAM multicarrier modulation. A phase reference pilot symbol of which a modulation amplitude is suppressed to zero, and an amplitude reference pilot signal obtained through modulation performed by using an amplitude known to a reception end are transmitted from a transmission end, and the transmission characteristic of the transmission channel is estimated and compensated by using the phase reference pilot signal and the amplitude reference pilot signal at the reception end. Thus, it is possible to simplify frame generation process performed at the transmission end, and reduce transmission power for the phase reference pilot signal.
