The mode competition is much improved. it may operated with a large electron beam radius, that means decreasing the space charge effects compared with a smaller radius beam with the same current, hence the rbwo may operated with a low axial guide magnetic field. besides, the rbwo with a sinusoidal corrugated coaxial structure is very easy to manufacture
波紋內導體rbwo具有一些突出優點:同軸結構中內導體的存在使系統的截止頻率顯著升高,使得系統尺寸可比普通波紋波導慢波系統大;具有很大的抑制模式競爭的能力和很高的功率容量;可以採用大半徑電子注,在工作電流不變的情況下空間電荷效應大幅度降低,因而可以工作在低磁場狀態;此種慢波結構內導體上的波紋易於加工。This paper gives us too ways : one is to adopt a better modulation mechanism, s - cdma, to bate noise jamming. the other way is to implement automatic frequency agility under strong noise, based on the ranging and burst configuration mechanism of current docsis protocol, meanwhile, guaranteeing cmts ' s normal operating. this paper comprehensively analyzes the anti - jamming mechanism of docsis, then presents the specific implementation of the latter method
如何降低噪聲對網路的危害,本論文指出了兩個方向,其中一個就是在調制體制上下工夫,採用s - cdma體制,通過改變調制方式來主動的抑制噪聲的影響;另一個方向就是基於現在協議提供的抗噪聲干擾的機制,充分挖掘測距機制和靈活的突發配置機制的抗干擾潛力,以不影響頭端設備的正常運行為前提,以它們為基礎實現能自動避開強噪聲干擾的頻率轉移。
