Abstract: 提出了GEO卫星通信系统中MF-TDMA信道分配算法C-BFD.与传统信道资源分配算法相比,C-BFD采用了基于优先组合的方式,利用用户信道请求大小以及信道结构的特点,通过分配过程中对用户信道请求进行组合并优先分配,来减少时隙碎片的产生.仿真结果表明,该算法能够有效降低系统阻塞率以及信道碎片对系统资源利用率的负面影响.
English Abstract: A channel allocation algorithm named C-BFD in MF-TDMA GEO satellite system was proposed. Comparing with the traditional channel allocation algorithms, C-BFD uses preferential combinition and allocates channel for users based on the characteristics of the channel structure and requested channel sizes. It reduces the channel fragmentation by combining users'requests which can fill up a complete carrier with the same frequency. The simulation result shows that this algorithm can effectively bring down the system block rate and channel fragmentation.
