摘要
随着TD-SCDMA无线通信系统商用的成熟,研究多核手机芯片的非信令模式符合终端测试发展需求。通过对TD-SCDMA下行同步过程的研究,设计了快速的非信令模式下行同步实现方案,同时结合多核手机芯片的特点充分优化下行同步过程的实现。实现结果表明,该下行同步方案处理时延40μs左右,频偏估计结果的均值和标准差分别稳定在10 Hz、32 Hz左右,能够用于简化多核终端生产测试过程,具有一定的工程应用价值。
With the maturity of TD-SCDMA wireless communication system, the research on TD-SCDMA no-signaling mode which is based on multi-core phone chip meets the demand of phone test development. With the research on TD-SCDMA downlink synchronization process, a no-signaling mode downlink syn-chronization scheme which is highly optimized according to the characteristics of muhi-core phone chip is designed. The implementation result shows that this scheme has low time delay （about 40 μs） and the mean and standard deviation of the frequency offset is 10 Hz and 32 Hz, respectively. The scheme can greatly simplify the process of terminal test.
