摘要
主要描述了北约陆军在战斗网中使用的标准波形(NBWF),该波形带宽是25k Hz,工作于VHF/UHF频段,支持多跳网络下的语音和IP数据业务,具备战术识别功能。主要阐述了波形子层的最重要机制,包括物理层、MAC层、LLC层和网络层,最后对该波形性能进行了评估分析。分析结果表明,该波形在链路吞吐量、组播语音中继和Qo S等方面都具备良好的性能。这些工作成果对未来波形设计具有一定的参考意义。
NBWF （Standard Waveform） used by NATO army in combat network is principally described. This waveform is 25 kHz in bandwidth and works in the frequency band of VHF/UHF, supports voice of multi-hop and IP data traffic, and thus could provide tactical identification. The most important mechanisms of the waveform sublayers, including physical layer, MAC layer, LLC layer and network layer are expounded. Finally the performance of this waveform is evaluated and analyzed, and the analysis result indicates that this waveform enjoys good performance at the link throughput, multicast voice relay and QoS. And all this is of certain reference significance for future design of waveform.
