Abstract(in English) It is very important to evaluate the characteristics of the mutual interference with the Mobile Systems and Fixed Service Systems, and also the Mobile satellite System (MSS) and existence satellite system when introducing IMT-2000 at 2-GHz band in the domestic market. The technical group which was organized by the Association of Radio Industries and Businesses had been investigated the mutual frequency interferences between IMT-2000 and other radio systems near IMT-2000 frequency band. We reported already on the study regarding the nonlinear interference between CDMA and Mobile Satellite Systems (MSS), by using the input level of intercept point (IIP). We also reported on the examination of interference between DS-CDMA and PHS. This paper presents the results of the theoretical study on the nonlinear interference level from wide-band mobile system to narrow-band mobile system by using input level of 3^-order intercept point (IIP3) as regarding CDMA system parameters. In the theoretical study, we analyze the nonlinear interference level, the spectrum spread of Inter-Modulation(IM) and the career level reduction factor. We also show the Bit Error Rate(BER) performance on Desired to Undesired signal ratio(D/U) between the examination results and the theoretical study.
