摘要
临近空间通信系统作为无线通信新的分支面临着为混合业务提供支持的问题,为此需要设计一种高效的多址接入协议以满足复杂的通信需求;在多频时分多址接入(MF-TDMA)协议的基础上提出了一种改进协议,通过对帧时隙进行功能划分,提出了固定时隙段加动态时隙段的设计,实现了对不同类型、不同速率业务的支持;利用OPNET仿真软件进行了系统建模和协议性能仿真,仿真结果验证了协议设计的合理性和有效性。
As a new branch of wireless communication system,near space communication system faced the problem of providing support for multi services,therefore,it is necessary to design an efficient multiple access protocol to meet the complex communication needs. An improved protocol based on multi-frequency division multiple access( MF-TDMA) was proposed,by dividing the time slots in two different parts,the design of fixed slots segment and the dynamic slots segment were proposed,which realizes the protocol well supports of the mixed services of different types and different rates according to different fuctions. OPNET simulation software was used to finish the system modeling and protocol performance simulation,and the simulation results verify the rationality and effectiveness of the protocol design.
