Abstract

In a skywave communication setting, a number of independent measurement techniques can be employed simultaneously and their results combined to yield a metric representative of the channel quality during a particular reception. This sample can then be combined with previous samples taken using the same frequency (or same frequency hop set in a frequency hopping system) to serve as a basis for selecting the best operating frequencies.
