Abstract: A communication apparatus includes a reference signal generating section, a transmitting section, a propagation estimating section, a first data acquiring section, and a decoding section. The reference signal generating section generates a first reference signal to enable a communicating party to estimate a propagation environment. The transmitting section transmits the first reference signal. The propagation estimating section estimates a first propagation estimation value of the propagation environment using a second reference signal transmitted from the communicating party. The first data acquiring section generates first data using the first propagation estimation value. The decoding section decodes a transmission signal encoded using a second propagation estimation value that is estimated by the communicating party using the first reference signal, to obtain second data using the first data.

Abstract: A transmission frame generating device includes a control information signal generator and a frame former. The control information signal generator generates a modulation method information signal indicating a modulation method of a data signal and an error correction method information signal indicating an error correction method of the data signal. The frame former forms the transmission frame by repeating and discretely arranging the same modulation method information signal on a first multiple of a plurality of subcarriers on a frequency axis and by repeating and discretely arranging the same error correction method information signal on a second multiple of the plurality of the subcarriers on the frequency axis.

Abstract: A transmission frame generating device generates a transmission frame. The generating device includes a control information signal generator which generates a modulation method control signal indicating a modulation method used for a data signal and an error correction method control signal indicating an error correction method used for the data signal and a frame former which forms the transmission frame by arranging a training signal, the data signal, the modulation method control signal and the error correction method control signal on a plurality of subcarriers on a frequency axis. The modulation method control signal being repeatedly and discretely arranged on a first multiple of the plurality of subcarriers on the frequency axis and the error correction method control signal being repeatedly and discretely arranged on a second multiple of the plurality of the subcarriers on the frequency axis.
