Abstract: An apparatus includes: first to N−1-th correlation-calculation units correlation-calculating a signal at a position corresponding to an n-th reference cell of a reference symbol in a received symbol and a signal at a position corresponding to an n+1-th reference cell of the reference symbol in the received symbol; a first calculation unit multiplying a result of phase correlation calculation of the n-th reference cell and the n+1-th reference cell by the calculation result of the correlation-calculation units and thereafter, summing up all of the multiplication results to calculate a first sum total; a second calculation unit multiplying a result of phase correlation calculation of an N−n−2-th reference cell and an N−n−1-th reference cell by the calculation result of the correlation-calculation units and summing up all of the multiplying results to calculate a second sum total; and a decider detecting a larger value between the first and the second sum total.
