ABSTRACT:
An interference measurement and evaluation system for accurately estimating an interference characteristic of a receiving side including nonlinear interference for a wireless communications system, having a transmission signal for wireless communication and an interference signal between an interfered side and the receiving side, provided with a nonlinear interfering side giving an interference signal having a level unable to be neglected compared with the level of the modulated carrier transmitted from the interfered side, and provided with an interference characteristic estimating means for estimating an interference characteristic including a nonlinear interference characteristic possessed by the receiving side in accordance with a received signal level and a received level when a nonlinear interference theoretical curve given in relation with the line quality satisfies a predetermined line quality.
