An eigenvalue decomposer(63) performs an eigen-decomposition with respect to the output of the covariance matrix estimator(61). An inner product arithmetic device(65) estimates at least two eigenvectors having relatively great values among eigenvectors corresponding to eigenvalue of the covariance matrix, as time-invariant vectors. A channel vector estimator(69) receives the time-invariant vectors obtained in the inner product arithmetic device(65) and a channel rank obtained using a previously known symbol, and estimates a channel vector. A beam forming vector arithmetic device(71) adds output signals of the channel vector estimator(69) to weight values.
