For the situation of 3G frequency allocation for the three operaters in China,the theoretic analysis and estimation of the interference between Time Division Synchronous Code Division Multiple Access(TD-SCDMA) and Personal Handy-phone System(PHS) is done.It is difficult to solve this interference in city by space isolation.The comparison of two interference-avoidance methods,including antenna vertical separation and filtering device,indicates that the antenna vertical separation is more effective than filtering device.This study provides a theoretical practical direction for the coexistence and development of TD-SCDMA and PHS systems.
