摘要
随着TD-LTE网络大规模的投入商用,其后续演进技术TD-LTE-Advanced受到越来越多的关注。由于载波聚合CA和UL-MIMO技术的引入使得对TD-LTE-Advanced终端信号分析成为了终端射频一致性测试的一个关键点。本文在分析了TD-LTE-Advanced终端频谱发射模板测量原理的基础上,提出了一种快速测量方法和硬件实现技术,并进行了实际测量实验。测量结果验证了所提方法的有效性。
With the wide applications of TD-LTE network in commerce, the TD-LTE-Advanced which evolves from the TD-LTE network is gaining more and more attention. Due to the introduction of carrier aggregation(CA)and UL-MIMO technology, the terminal signal analysis of the TD-LTE-Advanced has become a key point of the terminal RF conformance testing. Based on the analysis of the principle of the TD-LTE-Advanced terminal spectrum emission template measurement, a fast measurement method and the hardware implementation technology are proposed, and a measurement experiment is carried out. The validity of the proposed method is verified by the measurement results.
