摘要
分析了3G之间的干扰问题,主要是TD-SCDMA对WCDMA、CDMA2000的干扰。通过对终端和基站干扰的分析以及对干扰强度的计算,得出了减少干扰的措施。同时,提出对基站加装带通滤波器的办法,并设计了一种作为WCDMA发射和接收滤波器的波导带通滤波器,以满足一定的插损要求。由于在设计过程中采用了一定的近似,并通过Ansoft仿真软件对参数进行优化,得出了带通滤波器的参数。仿真结果表明,该设计的带通滤波器能很好地满足设计要求。
This paper analyzes the interference between 3G, principally the interference of TD-SCDMA on WCDMA and CDMA2000. Based on interference analysis of terminal and base-station, and the intensity calculations of interference, the measures for reducing the interference are acquired, the adding of bandpass filter to base-station is proposed, and a waveguide band-pass filter as the filter for WCDMA transfer and receive is also designed, thus to meet the requirements of certain insertion loss. With certain approximation in the design process and the parameter optimization by Ansoft simulation software, the band-pass filter parameters are obtained. The simulation results indicate that the proposed of band-pass filter could fairly meet the design requirements.
