<p>PROBLEM TO BE SOLVED: To provide a multi-carrier wireless transmission system that can estimate a channel with high accuracy in a state where various fluctuations take place in the state of wireless transmission channel. SOLUTION: When a channel with respect to each subcarrier is estimated in the multi-carrier wireless transmission system where information is wirelessly transmitted by using n-sets of subcarriers, a received signal including m-sets (m<=n) of subcarrier components to which a pilot symbol is inserted is separated into each subcarrier component, using the pilot symbol included in the obtained subcarrier component estimates a channel with respect to the subcarrier to obtain the result of estimation of each channel, and the channel is estimated with respect to the estimate object subcarrier on the basis of the relation among the individual channel estimate result with respect to each of p-sets (p<=m) of subcarriers, a state of a transmission channel with respect to the estimate object subcarrier and the state of a transmission channel of each of the p-sets of subcarriers.</p> |
