摘要
基于时分同步码分多址复用技术的标准作为我国自主研发的第三代移动通信标准之一,已进入广泛应用阶段。针对TD-SCDMA信号物理层的空间接入过程,采用了先进设计系统(ADS)对TD-SCD-MA通信系统进行设计仿真,着重论述了无线信道和高斯白噪声的设计和实现,仿真结果均符合3GPP协议的规定。研究结果表明,该研究为意义上的无线通信研究提供了方法和理论依据。
As a kind of 3G communication standards, TD-SCDMA was invented by our own country and had been applied extensively. Aiming at the process of space access of TD-SCDMA physical layer, the communication system was designed by ADS, in the system, the transmission environment was simulated by designing wireless channel and Gaussian white noise. The results are in line with the provisions of 3GPP, which indicate that the analysis provides methods and theoretical basis for future research.
