摘　　要：本文讨论了卫星移动通信中由于ＮＧＳＯ／ＭＳＳ馈送链路与ＧＳＯ／ＦＳＳ共享频率而引起的干扰问题，作为解决手段引入了反向频率工作模式。通过对具体数据的分析表明，这一模式可以有效地减轻两个系统之间的干扰，是协调ＮＧＳＯ与ＧＳＯ间干扰的一种最具吸引力的方案。This paper has discussed the interference which results from frequency sharing between NGSO/MSS feeder links and GSO/FSS.And the reverse band working mode(RBWM) is introduced to deal with the interference. The numerical analyses using engineering data is carried out.And the results show that RBWM is an effective means for providing MSS feeder links in frequency bands shared with the FSS, without the need for coordination.
