摘　　要：TD-LTE(time division-long term evolution)无线资源管理一致性测试是检验TD-LTE终端是否符合协议标准的重要手段。鉴于传统一致性测试平台存在不足之处,无线资源管理一致性测试搭建了基于TTCN-3(testing and test control notation version 3)的一致性测试平台,并分析了该测试平台相对于传统测试平台的优越性。利用TTCN-3软件编写测试例并进行测试。通过分析测试流程图可以得出,一致性测试平台的可行性,并验证了该平台相对于传统平台的优越性。In parking-lot applications, in order to improve anti-interference ability of UWB indoor positioning detection with multiple users, the paper puts forwards an improved algorithm of orthogonal variable spread factor （OVSF-TH） in which spread factor is automatically matched with the size of interference. Meanwhile, to further improve the positioning accuracy, the paper also proposes a joint detection method, which combines with two traditional algorithms, i.e. maximum-likelihood estimation algorithms based on RSS（residual sum of squares） and improved algorithms based on least-squares. Simulation results show that the positioning accuracy of the joint detection method is superior to traditional algorithm, so, it is also suitable for other UWB positioning applications.
