INTERFERENCE MEASUREMENT EVALUATING SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an interference measurement evaluating system for accurately estimating the interference characteristics of a receiver side including non-linear interference to a radio communication system. <P>SOLUTION: The interference measurement evaluating system has a transmission signal for performing radio communication and an interference signal between a transmitting means (101) and a receiving means (102), and is provided with a non-linear interference means (103) for giving an interference signal having a level that cannot be ignored compared to the level of a modulation carrier wave to be sent from the transmitting means. The system is provided with an interference characteristic estimating means (20) for estimating interference characteristics including the non-linear interference characteristics owned by the receiving means, according to the receiving level at which a non-linear interference theory curve given in relation to the reception signal level and line quality satisfies predetermined line quality. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
