Abstract : There is currently an urgent need for alternate channels for communication. The large variety and quantity of users throughout the world have caused all of the existing channels to become extremely congested. A world wide search for such alternate channels is now being conducted for both present day and future communication systems through the use of different types of channels such as optical, laser, cable, satellite, etc. The particular application of Beyond-Line-of-sight (BLOS) communications, which uses the High Frequency (HF) spectral band from 3 to 30 MHz, is very important to many current and potential users. However, HF is very sensitive to solar disturbances such as sunspot activity, solar storms and other galactic phenomena, as well as multipath returns from both ground and atmosphere, weather related attenuation, and other degrading factors. Because of these factors a channel for communication is needed which has low congestion, is robust and relatively indestructible, has very little outside interference and does not compete for bandwidth with existing communication systems.
