    摘要: According to one embodiment, a channel phase estimation apparatus includes a phase memory, subtractor, multiplier, and adder. The phase memory is configured to store a first phase estimation value up to a (k−1)-th (for k=1, 2, . . . , K) symbol. The subtractor is configured to calculate a difference value between a phase value of one carrier of a k-th symbol and the first phase estimation value. The multiplier is configured to multiply the difference value by a weight. The adder is configured to add a value output from the multiplier and the first phase estimation value to output a second phase estimation value up to the k-th symbol.
