Patent ID: 8576902

Claim:
A receiving device comprising: a receiver configured to receive a signal that is transmitted via a propagation path and is modulated by a predetermined system prescribed by a predetermined standard; a demodulator configured to demodulate the received signal; an estimator configured to estimate a signal-to-noise ratio relating to the propagation path, obtained from a data signal included in the demodulated received signal; a corrector configured to correct the estimated signal-to-noise ratio in accordance with a transmission parameter obtained from the received signal; and an acquirer configured to acquire a correction parameter that is associated with the transmission parameter on each transmission parameter basis and is used for correction of the estimated signal-to-noise ratio, wherein the corrector performs predetermined calculation with use of the acquired correction parameter to approximate a value of the estimated signal-to-noise ratio to a value of a path signal-to-noise ratio of the propagation path, wherein the correction parameter includes a first variable indicating the amount of correction of a slope of the estimated signal-to-noise ratio on a logarithmic axis of the path signal-to-noise ratio and the estimated signal-to-noise ratio, and a second variable indicating the amount of correction of an intercept of the estimated signal-to-noise ratio, and the corrector performs second calculation of multiplying, by the second variable, a value obtained by raising the estimated signal-to-noise ratio as a true value to the power of the first variable, to correct the estimated signal-to-noise ratio so that the path signal-to-noise ratio and the estimated signal-to-noise ratio have a proportional relationship.
