| 摘 要： | 根据TD-SCDMA码资源特点,在深入分析复合码循环相关特性的基础上,提出了归一化码字相关值的概念,作为衡量扰码互相干扰的相关特性值,以此为依据可以构建扰码对的互相关值评价矩阵。并在3GPP TS25.102协议给出的1.28 Mc/s TDD的三种多径衰落信道环境下,进行扰码规划算法的仿真测试。研究表明,TD-SCDMA系统的扰码间相关值越小系统性能越好。

| Abstract: | According to the features of code resource in TD-SCDMA system,the paper,based on analysis of scrambling-code circular correlation,proposes the concept of normalized symbol correlative value,and with this value as mutual disturbance,the weight of code disturbs mutually,the evaluation matrix of cross-correlation value for scrambling-code is constructed.In the 1.28 Mc/s TDD of 3GPP the TS25.102 protocol,the scambling-code planning algorithm is simulated under the three multi-path fading channel environments.Th... |
