<P>PROBLEM TO BE SOLVED: To provide a line quality characteristic evaluating system for estimating line quality characteristics under an interference environment including non-linear interference for a radio communication system including at least one interference-imparting radio line. <P>SOLUTION: The line quality characteristic evaluating system is provided with a line quality estimating means (7) for estimating the line quality of a radio communication line under a non-linear interference radio line, in an area where radio communication lines and interference-imparting radio lines corresponding to these are mixed, on the basis of non-linear distortion which is to be influenced by all the radio lines and is expressed by an intercept point input level (IIP), a reception equivalent bandwidth limit expressed by an attenuation amount of the intercept input level (IIP), reception side thermal noise of the radio communication lines, and a leakage current leaking into a reception equivalent bandwidth from another radio line giving interference. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
