Interference is one of key issues for wireless network optimization. How to work with other communication systems is a crucial issue to ensure system performance in 3G networks. This article focuses on the analysis of adjacent channel interference between TD-SCDMA and WCDMA system. The interference mathematical model was discussed, including spurious interference, intermodulation and blocking interference. The minimum coupling loss was obtained by using deterministic algorithm in order to two system coexistence and co-station., the conclusion indicated that the necessary isolation require at least 33.87 and 69 dB, which have certain significance for engineering practice.
