  This paper 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.
