| Abstract: | According to the standard specifications of TD-SCDMA and WCDMA, the mutual interference of the systems TD-SCDMA and WCDMA with each other was theoretically analyzed when the both system sites are located at a common geographical region or they use commonly a system site, the investigation methodology of FDD/TDD system coexistence was expounded,the relative capacity loss due to FDD/TDD interference was simulated,and the solution method for the engineering practice was given. |

| Keywords: | additive interference blocking interference intermodulation interference WCDMA system TD-SCDMA system capacity coexistence co-location |
