As one of the key technologies of HF communication, the maximum usable frequency (MUF)
prediction method has been widely discussed. To experimentally confirm the reliability of …

Sensor networks have become more popular in recent years, now featuring plenty of options
and capabilities. Notwithstanding this, remote locations present many difficulties for their …

The ionosphere is the ionized part of the Earth's atmosphere, ranging from about 60 km up
to several Earth radii, whereas the upper part above about 1000 km height up to the …

Ionospheric modelling is one of the major tools to study the behavior of the ionosphere.
Ionospheric models have been useful in predicting the true state of the ionosphere …

The critical frequency foF2 is an important parameter of the ionosphere, but its measurement
data are often absent, especially during disturbances caused by the impact of space …

In the last couple of years, the use of weak signal propagation reporter (WSPR) has grown
significantly in the radio amateur community and beyond. This protocol allows to probe …

The Multi-Carrier Modulation (MCM) technique in the Near Vertical Incidence Skywave
(NVIS) propagation mode poses a challenge due to the ionosphere's dynamic behavior. The …

This paper critically examines the causes of attenuation of radio waves when it is
propagating through ionosphere. The electron density of ionosphere affects the propagation …

The development of a digital high‐frequency (HF) radio communication system requires an
ionospheric channel model from the channel impulse response (CIR) measurement …

The ionosonde is one of the most widely used ionospheric detection device. It has significant
implications for the study of space physics and wireless communication technology. To solve …
