摘要 |
A receiving device receiving a SC-FDMA signal includes a first calculating unit calculating a first channel estimation value indicating a propagation path state based on a sounding reference signal transmitted from a transmitting end device; a second calculating unit calculating a rank determination value and a modulation and coding scheme (MCS) determination value based on the first channel estimation value, the rank determination value and MCS determination value being associated with a transmission rank number and a transmission coding ratio/modulation scheme respectively, and used when the transmitting end device next transmits a data channel; a third calculating unit calculating a second channel estimation value indicating a propagation path state based on a demodulation reference signal by using interpolation processing in accordance with at least one of the rank determination value and the MCS determination value; and a demodulation/decoding unit acting on a data channel using the second channel estimation value. |

1. A receiving device that receives a single carrier-frequency division multiple access (SC-FDMA) signal, the receiving device comprising:
first calculating unit that calculates a first channel estimation value indicating a state of a propagation path, on the basis of a sounding reference signal transmitted from a transmitting end device; second calculating unit that calculates, on the basis of the first channel estimation value, a rank determination value associated with a transmission rank number and a modulation and coding scheme (MCS) determination value, which are used when the transmitting end device transmits a data channel next; third calculating unit that calculates a second channel estimation value indicating a state of a propagation path, on the basis of a demodulation reference signal, by using interpolation processing in accordance with at least one of the rank determination value and the MCS determination value; and an unit that performs demodulation and decoding of a data channel by using the second channel estimation value. |
