摘　　要：在有限时间内高效分配信道资源是MF-TDMA卫星通信系统高效工作的保证。在分析周期轮询法分配信道策略的时间浪费缺点基础上,根据信道分配不同阶段的特点,提出了时隙列表法,通过分配过程中的一次轮询,创建时隙列表记录信道空闲时隙的分布信息进行分配,并对时隙列表实时维护,避免对已分配时隙的检测,以大幅缩短分配的时间。最后通过仿真比较,验证了这一方法的可行性与高效性。An efficient channel assignment scheme makes MF-TDMA satellite communication systems work efficiently. The periodic-detecting scheme has a disadvantage of wasting time. In order to avoid the disadvantage, an efficient optimization scheme is introduced according to different characteristics during the assignment. The timeslot-list records information of idle timeslots by searching the channel once to predigest the search. The idle timeslots in channel are assigned by timeslots-list that needs to be modified with any change. The emulation results show that the scheme is feasible and efficient.
