Abstract:
1. A communication apparatus, comprising: a reference signal generating section that generates a first reference signal to enable a communicating party to estimate a propagation environment; a transmitting section that transmits the first reference signal; a storing section that stores a known signal known between the apparatus and the communicating party a propagation estimating section that obtains correlation between the known signal and a second reference signal transmitted from the communicating party, and generates a delay profile as an estimation value of propagation environment; a first data acquiring section that reads out first data associated with the delay profile generated in the propagation estimating section, from a reference table that associates the delay profile with the first data; and a decoding section that decodes a transmission signal encoded and transmitted using an estimation value of the propagation environment estimated by the communicating party using the first reference signal, to obtain second data using the first data read out by the first data acquiring section.
