这封信提出了一个开创性的研究的基础上，一系列的实验操作的商业时分长期演进（TD-LTE）系统的脉冲干扰信号的存在下，在3550-3650 MHz频段。在与高功率SPN-43雷达重叠和相邻的信道中进行TD-LTE操作，两个系统之间具有不同的频率偏移，以评估LTE对高功率干扰信号的敏感性。我们的研究结果表明，使用低天线高度的LTE通信不会受到在相邻频率上操作的脉冲干扰信号的不利影响，而不管干扰发射机的距离如何。只有在干扰发射机的重叠频率非常近的距离（1-2公里）时，性能才会下降。
This letter presents a pioneering study based on a series of experiments on the operation of commercial Time-Division Long-Term Evolution (TD-LTE) systems in the presence of pulsed interfering signals in the 3550-3650 MHz band. TD-LTE operations were carried out in channels overlapping and adjacent to the high power SPN-43 radar with various frequency offsets between the two systems to evaluate the susceptibility of LTE to a high power interfering signal. Our results demonstrate that LTE communication using low antenna heights was not adversely affected by the pulsed interfering signal operating on adjacent frequencies irrespective of the distance of interfering transmitter. Performance was degraded only for very close distances (1-2 km) of overlapping frequencies of interfering transmitter.
