PROBLEM TO BE SOLVED: To contribute to improvement of estimation accuracy of a propagation path without sacrifice of throughput of data transfer in communication technology by OFDM.SOLUTION: In a plurality of symbols (SMBL) constituting a slot (SLT_adv), a series of known signals (SIGDIV_ref) for estimating the propagation path of wireless communication is arranged in regions α, β while being divided. In other words, a symbol is generated by combining an information signal and the known signal and arranged in a slot. Since a series of known signals assigned to one symbol is arranged in each symbol while being distributed, the propagation path can be estimated in units of symbol. Followability of propagation path estimation is improved by estimating the propagation path in units of symbol.
