A comparison between frequency hopping and direct spread pn as antijam techniques
Marc Spellman · IEEE Communications Magazine · 1983
FREQUENCY Hopping (FH) and Direct Spread Pseudonoise (PN) are the signal processing techniques most often used to achieve an antijam capability. However, comparisons between the techniques in order to determine relative superiority have often been marred in the past by one-sided defenses of one technique or the other. In this paper, an unbiased and comprehensive comparison between the two techniques is presented. The comparison is based on the premise that neither technique is categorically superior, and compares the relative merit of the two techniques for each of a number of issues relevant to antijam systems. By noting both the important issues for a particular application and the relative performance of the two techniques for those important issues, support can be provided for the process of selecting the appropriate technique.
