The study is conducted under a set of guidelines concerning digital message error rates, message structure, communication link distance, frequency, multiple access capability (i.e., self-interference) and processing gain against intentional jamming. Pseudonoise, time hop, frequency hop, and hybrid modulation techniques are examined and only two are found to be suitable for satisfying the study guideline: frequency hop and time hop/pseudonoise.
