A STUDY OF HIGH FREQUENCY COMMUNICATIONS IMPROVEMENT TO OVERCOME THE IMPACT OF MINIMUM SOLAR ACTIVITY
Abstract
The impact of the solar cycle minimum on selected high frequency communication trunks of the Defense Communications Systems for assumed running average sunspot numbers of 100, 50, and 5 is studied. The impact is defined as the percentage of time when none of the assigned frequencies will provide communications on the trunk in question within the limits imposed by the combined effects of propagation conditions, noise levels, and system parameters. Impact determination for a specific trunk was principally a problem in propagation, although the characteristics of system equipments also were considered. (Author)
