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