Multi-Level Locally Orthogonal Frequency Hopping Mode Division Multiple Access (MLLO-FH-CDMA) is introduced as a novel method to reduce self-interference in large scale FHCDMA ad hoc networks. It is analyzed in a stochastic geometry scenario and verified with simulations. The performance gains of multi-level hopping are shown by comparing it to standard FH-CDMA channel access. Frequency Hopping Code Division Multiple Access (FHCDMA) systems are widely applied in military communications due to the inherent robustness against external interference created by, e.g., deliberate signal jamming and to decrease the probability of signal interception.
