We analyze a scheme that provides frequency hopping pattern for DS/FH spread spectrum. The proposed scheme, based on the theory of finite projective planes, intends to make the number of transmitting terminals uniform across all channels and distribute the interference to all the participant terminals equally. Thus, when a terminal is in a state of power surge, the probability of having the worst case of interference for terminals sharing the same channel is reduced. In the performance evaluation, we demonstrate that the bit error rate is reduced by an order of magnitude through the use of the proposed hopping pattern for both internal and external interference.
