First, this paper studies the separation of shortwave calling channels and service channels, orthogonal grouping of frequency set, synchronized scanning and rapid frequency choosing, and nonlinear frequency scanning. These are the four foundations needed to realize frequency spectrum sharing. Then, we explore a way to realize dynamic sharing of military… (More)
Starting from analyzing the necessity of military shortwave frequency planning, this paper illustrates its usable frequency set planning, working frequency subset planning and frequency pattern planning. It also studies the relative planning ways that have theoretical significance for realizing dynamic frequency management of military shortwave.
