【摘要】：干扰一直是移动通信系统中一个重要的课题，是影响移动通信系统的重要因素，其本质就是未按频率分配规定的信号占据了合法信号的频率，影响合法信号的正常工作，这也就产生了不同系统间的共存问题。随着计算机和通信技术的迅猛发展，各种系统之间的共存将会长期存在。 作为中国移动运营商采用的第三代系统方案，，具有中国自主知识产权的TD-SCDMA在中国的建网已经不断的完善，而TD-LTE是TD-SCDMA的自然演进路径。在中国政府和中国移动以及产业界的共同努力下，TD-LTE将有更广阔的前景，因此，研究TD-SCDMA与TD-LTE的共存干扰具有实际意义。 本文主要介绍了在大唐电信研究TD-SCMDA和TD-LTE两个系统共站和非共站的干扰问题。采用确定性分析法和蒙特卡洛系统仿真法，对TD-SCDMA与TD-LTE两系统之间干扰问题进行研究。 本文先采用确定性分析法，初步计算出这两个系统之间在不同频段时杂散干扰的情况。通过合理的时隙配置，使得两个系统同步，规避基站间的干扰。然后采用静态仿真方法，对两系统宏小区在共站和非共站的场景下进行仿真，得出仿真的结果，对TD-SCDMA系统和TD-LTE系统的混合组网具有重要的参考价值。
[Abstract]:Interference has always been an important subject in mobile communication system and an important factor affecting mobile communication system. Its essence is that the signal which is not assigned according to the frequency has occupied the frequency of the legitimate signal and affected the normal operation of the legitimate signal. This also gives rise to the problem of coexistence between different systems. With the rapid development of computer and communication technology, the coexistence of various systems will exist for a long time. As the third generation system scheme adopted by Chinese mobile operators, TD-SCDMA with China's own intellectual property rights has been continuously improved in China, and TD-LTE is the natural evolution path of TD-SCDMA. With the joint efforts of the Chinese government, China Mobile and industry, TD-LTE will have a broader prospect. Therefore, it is of practical significance to study the coexistence of TD-SCDMA and TD-LTE. This paper mainly introduces the co-station and non-costation interference of TD-SCMDA and TD-LTE in Datang Telecom. The interference between TD-SCDMA and TD-LTE systems is studied by deterministic analysis and Monte Carlo system simulation. In this paper, deterministic analysis method is used to calculate the stray interference between the two systems at different frequency bands. Through reasonable time slot configuration, the two systems are synchronized to avoid interference between base stations. Then the static simulation method is used to simulate the two system macro cells in the co-station and non-co-station scene. The simulation results show that the simulation results have important reference value for the hybrid networking of TD-SCDMA system and TD-LTE system.
