Performance Analysis for Multiple Access of the Mobile-Cellular Model

  • 摘要: 提出了一种适合于武器协同数据链的移动蜂窝模型,并针对该模型提出了基于离散FDM的FHMA/CDMA相结合的多址接入方式。该方式理论上能够为无穷多的参与平台提供服务,且具有较低的发送延迟。该文对基于离散FDM的FHMA/CDMA相结合的多址接入方式的数据分组成功发送率、网络吞吐量以及信息时延等性能指标进行了理论分析,并仿真分析了码分信道数、扩频增益等主要参数对网络性能所产生的影响。结论表明,所提出的多址方式具有较好的接入性能,能够满足武器协同数据链网络的低时延应用需求。
    Abstract: The mobile-cellular model for weapon cooperation data link (WCDL) is proposed. The frequency hopping/code division multiple access (FH/CDMA) for this model is studied based on discrete frequency division multiplexing (FDM). Theoretically, the multiple access technology can sustain the service for infinite users and provide low delay service. The performances of success rate, throughput, and delay are analyzed. The influences of the main parameters such as the number of channels and the gain of spreading spectrum are simulated. The results demonstrale that the multiple access technology can meet the low delay application request of WCDL with better performances.
