Transmitting apparatus, receiving apparatus, transmission method, and reception method
A transmitting apparatus controls, for each transmit frame, at least one of a modulation method and an error correction method. The transmitting apparatus forms an information symbol and transmits the information symbol using multiple subcarriers. A modulation method information signal generator generates an information signal relating to a modulation method of the information symbol. An error correction method information signal generator generates an information signal relating to an error correction method of the information symbol. A frame former forms a transmit frame by repeating and discretely arranging at least one of the same modulation method information signal and the same error correction method information signal at the same time within the same frame, and a transmitter transmits the transmit frame.
1. A transmitting apparatus that controls, for each transmit frame, at least one of a modulation method and an error correction method, and that forms an information symbol and transmits the information symbol using a plurality of subcarriers, the transmitting apparatus comprising:
a modulation method information signal generator that generates an information signal relating to a modulation method of the information symbol;
an error correction method information signal generator that generates an information signal relating to an error correction method of the information symbol;
a frame former that forms a transmit frame by repeating and discretely arranging at least one of a same modulation method information signal and a same error correction method information signal at the same time within the same frame; and
a transmitter that transmits the transmit frame.
2. The transmitting apparatus according to claim 1 ,
wherein-said frame former repeats and arranges at least one of the same modulation method information signal and the same error correction method information signal using a plurality of consecutive subcarriers at separate locations at the same time on a frequency axis.
3. A transmission method that controls, for each transmit frame, at least one of a modulation method and an error correction method, and that forms an information symbol and transmits the information symbol using a plurality of subcarriers, the transmission method comprising:
generating a modulation method information signal relating to a modulation method of the information symbol and generating an error correction method information signal relating to an error correction method of the information symbol;
forming a transmit frame by repeating and discretely arranging at least one of a same modulation method information signal and a same error correction method information signal at the same time within the same frame; and
transmitting the transmit frame.
4. The transmission method according to claim 3 , further comprising:
repeating and arranging at least one of the same modulation method information signal and the same error correction method information signal using a plurality of consecutive subcarriers at separate locations at the same time on a frequency axis.
