    High Frequency Radio Group (HFRG) is a fully automated subsystem of the external radio communications system (RCS) aboard surface ships. The HFRG operates in the Very Low Frequency (VLF), Low Frequency (LF), Medium Frequency (MF) and High Frequency (HF) bands and supports full duplex, half duplex and simplex operation for tactical and long-haul.

This report describes a model for errors occurring over high-frequency (HF) propagation channels that employ the FED-STD Automatic Link Establishment (ALE) modem. It is part of a series of three NTIA reports on a software package that simulates the various components of high-frequency radio automatic link establishment.

- 1 - CHAPTER 1 INTRODUCTION Intent of Handbook. An oblique ionogram is a plot of the signal power at the receiver as a function of operational frequency and group delay range.

The investigation of HF propagation based on oblique soundings enables the determination of the main characteristics of the radio channel, for example maximum and minimum observing frequencies and the range of the optimal frequencies for HF radio by: 5. the paths of high frequency radio waves.

The main effect of the D layer is to attenuate high frequency waves when the transmission path is in sunlit regions. l E—used during the day for high frequency radio transmission over intermediate distances (less than 2, km [1, mi]).

2 The wireless channel A good understanding of the wireless channel, its key physical parameters and the modeling issues, lays the foundation for the rest of the book. This is the goal of this chapter. A defining characteristic of the mobile wireless channel is the variations of the channel strength over time and over frequency.

Just like a pipe has a certain diameter, an RF channel has frequency bandwidth or channel spacing. Wideband channels occupy 25 kilohertz of radio spectrum. A narrowband channel is half that size and occupies kilohertz.

Ultra narrowband is half the size again at kilohertz, and it. 09 X X X Boater Calling Channel, Commercial & Recreational 10 X X X Commercial 11 X X X Commercial, VTS (Selected areas) 12 X X X Port Operation, VTS (Selected areas) 13 X X X Intership Navigation Safety (bridge-to-bridge) 14 X X X Port Operation, VTS (Selected areas)File Size: KB.

Impulse Response Model of a Multipath Channel A mobile radio channel may be modeled as a linear filter with a time varying impulse response, where the time variation is due to receiver motion in space.

The filtering nature of the channel is caused by the summation of amplitudes and delays of the multiple arriving waves at any instant of Size: 1MB. Radio propagation – the eletromagnetic phenomenom discovered by Henrich Hertz in the late ’s.

In wireless systems, fading may either be due to multipath propagation, referred to as multipath-induced fading, weather (particularly rain), or shadowing from obstacles affecting the wave propagation, sometimes referred to as shadow fading.

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 to 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred metres).Frequency range: 3 to 30 MHz.
