In this paper

the throughput of unslotted FH-CDMA system is evaluated. As the channel traffic and the number of frequency slots

denoted by μ and q respectiv ely

approach infinity while μ/q remains constant

it is shown that the throughput of unslotted FH-CDMA system is the same as that of slotted system

and the maximum throughput of synchronous frequency-hopping system is twice that of asynchronous system. Besides

the numerical results show that it is a better way to employ unslotted system as compared with slotted system.
