An optimum channel input-tra¦c control (OCIC) scheme is proposed and investigated for slotted frequency-hopped
spread spectrum multiple access communication systems. The conditional throughput is obtained, the state transition
probability is derived, the steady-state throughput is obtained, and the mean packet delay is calculated. It is shown that
the performance of the OCIC scheme is better than that of other schemes. It is also shown that the smaller the number of
frequency slots is, the more the OCIC scheme outperforms the other schemes.
