Abstract
A difference between DELAY values of paths is compared and when the difference is below a predetermined value, the paths are assumed to be the same and SIRs estimated for these paths are compared to each other. The SIRs are multiplied by corresponding weighting coefficients and are added in an SIR addition circuit. This eliminates erroneous recognition of one path as a plurality of paths, causing an enormous SIR after the addition and prevents deterioration of the line quality.
