本文通过ADS软件与MATLAB软件对系统进行建模和仿真，根据TD-SCDMA物理层信道协议和移动通信典型物理信道特征为理论依据，在软件ADS中搭建了专用物理信道电路与主公共控制信道电路，对物理信道中设计所用到的数据调制、扩频和加扰等功能模块进行了研究，逐一进行仿真分析，并且不断进行数据的比较与计算，确保每一个模块数据的正确性，直至最终重现TD-SCDMA的信号结构，并保证该生成的TD-SCDMA信号在物理层的帧结构上和TD-SCDMA协议一致。

This paper uses ADS and MATLAB software system to do some modeling and simulation, as the basis of TD-SCDMA physical layer channel protocol and typical physical channel characteristics in mobile communications, build a dedicated physical channel circuit and a primary common control channel circuit by ADS software, and make a further reach on data modulation, spread spectrum and scrambling these important functional modules. What's more, repeat make comparison and calculation of data to ensure the correctness of each module data, until eventually reproduce the structure of TD-SCDMA signal, and ensure that the physical layer frame structure of TD-SCDMA signal that generated is meeting the TD-SCDMA protocol.
