Proposed is a new approach for identifying, in a short time, the order information of data carried by a position measurement signal. In a baseband processing circuit unit (20), a parity check unit (214) performs, on the basis of a parity bit included in a first received subframe received thereby, a first determination as to whether any error has occurred in the first subframe. If it has been determined by the first determination that an error has occurred, the parity check unit (214) performs, on the basis of a parity bit included in a second received subframe adjacent to and immediately preceding the first subframe, a second determination as to whether any error has occurred in the second received subframe. If it has been determined by the second determination that no error has occurred, an order information identification unit (216) determines that the subframe ID of the second subframe is correct. |
