【摘要】 本文提出了一种计算非时槽FH-CDMA系统吞吐量的方法,并进一步证明了当信道业务量μ和频率槽数q趋于无穷,且μ/q保持常数时,时槽FH-CDMA系统的吞吐量与非时槽系统一致,但同步跳频系统的最大吞吐量是异步跳频的两倍。数值结果表明,就吞吐量和系统复杂性而言,采用非时槽系统比采用时槽系统更合适。更多还原

【Abstract】 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.更多还原
