A reception quality measuring apparatus (100) including: an equalizing processing unit (1) for performing an equalizing process on a reception signal to derive an equalized reception signal; lattice distance estimating element (2) for deriving a lattice distance estimation value using the equalized reception signal; an RSSI estimating unit (3) for deriving an RSSI estimation value using the lattice distance estimation value; an ISSI estimating unit (4) for deriving an ISSI estimation value by subtracting the RSSI estimation value from the lattice distance estimation value; and a dividing unit (5) for deriving an SIR representing reception quality by dividing the RSSI estimation value by the ISSI estimation value. |
