Abstract

Military communication systems require waveforms that are resilient in the presence of jamming signals (i.e. are antijam (AJ)), that have a low probability of detection (LPD) by unintended receivers, that have a low probability of intercept (LPI) by hostile receivers, and that operate well in the presence of many authorized users. Current spread spectrum communication techniques such as standard frequency hopping (FH) and direct sequence spread spectrum (DSSS) do not provide signals that simultaneously exhibit AJ, LPD, and LPI properties, allow conferencing, and are easily implemented. A newly proposed multiple access differential frequency hopping (DFH) communications system demonstrates improved AJ and LPD performance when compared to existing spread spectrum techniques. In addition, it successfully detects and decodes multiple (interfering) users in an architecture that is ad hoc and is easily implemented. Preliminary analysis and simulation results demonstrating the improved performance are provided.
