摘　　要：提出了通过压缩TD-SCDMA载波间隔来增加载波资源的方法,以缓解目前频率资源不足和干扰突出的问题,并通过系统仿真、实验室测试、外场测试等工作验证了TD-SCDMA载波间隔压缩至1.4MHz的可行性,明显提高频率使用效率,可以用于降低TD-SCDMA系统的同频干扰,也可以用于提高TD-SCDMA系统的网络容量。Put forward the compression of frequency sub-carrier in order to increase the frequency resource. The invention had experienced system simulation, lab test, and out door test, and had been testified that 1.4MHz band of sub-carrier is feasible the thought of the invention is adjustment of sub-carrier band in order to increase the frequency efficiency and to decrease the same frequency interference. The invention is also used to increase the capability of TD-SCDMA-SCMDA network.
