Abstract :
Multi-level locally orthogonal frequency hopping code division multiple access (MLLO-FH-CDMA) is introduced as a novel method to reduce self-interference in large scale FH-CDMA 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.
