基于联合检测在时分同步码分多址技术中的多径干扰分析

Multi-path Interference Analysis Based on the Joint Detection of TD-SCDMA

针对商用3G移动通信系统中,特别是成熟度缺陷的时分同步码分多址技术系统中多径干扰问题,提出一种新的联合检测技术。通过理论分析和系统仿真分析,新的联合检测抗多径干扰技术可以直接对系统终端和中心设备进行固件或软件版本升级完成优化,并可以根据系统中的设备不同性能配置,采用自适应算法以匹配。

In cases of the third generation mobile communication technology（3G） has been commercial,the problem of the multi-path interference still exists.Especially in TD-SCDMA system,due to the defect of maturity,the current commercial system still need further optimization to eliminate multi-path interference.So in order to solve this problem,in this paper a new joint detection technology is presented.Theoretical analysis and simulation analysis show that the new anti-multi-path interference technology is feasible and effective,which can directly upgrade firmware or software version for the terminal system and equipment and can adopt appropriate adaptive algorithm to match different properties and configuration of the equipment.
