摘要
随着3G通讯系统迅猛发展,特别是在TD-SCDMA系统中存在着各种干扰问题,影响和制约了系统本身容量和性能的提高。以多径干扰为例,首先通过理论和实验分析,提出一种新的抗干扰联合检测技术来消除多径干扰,然后在现有的硬件设备和系统软件配置基础上,通过比较分析两种自适应算法,选择采用合适的算法来完成TD-SCDMA系统的优化和升级,有助于提高系统容量和信道正交质量。
With the rapid development of 3G communication systems,especially in TD-SCDMA system,there are all sorts of interference problems,influence and restrict the improvement of the system capacity and performance.For example,multipath interference,first through the theoretical and experimental analysis,a new joint anti-interference detection technology to eliminate multipath interference,and then in the existing hardware and system software configuration on the basis of comparative analysis of two adaptive algorithm,select the appropriate algorithm to complete the optimization and upgrading of the TD-SCDMA system,help to improve the quality of system capacity and channel orthogonality quality.
