目前,国内外对多系统有重叠复盖的移动通信无三阶互调选频尚没有成熟的方法.本文针对多系统有重叠复盖的移动通信无三阶互调频率分配的问题,基于互调频率的筛选与方案比较,提出NMD选频原则和算法,可以解决各类无线组网问题,并提供新的理论依据和利用电子计算机进行辅助设计的手段.采用NMD方法不仅能缩短设计周期,而且能充分、合理地利用频率资源,有效地提高通信质量.
At present, there is not a mature method for third-order intermodulation frequency selection in mobile communications with overlapping coverage in multiple systems at home and abroad.This paper aims at the problem of no third-order intermodulation frequency assignment in mobile communication with overlapping coverage in multiple systems, Compared with the scheme, the NMD frequency selection principle and algorithm are proposed, which can solve all kinds of wireless networking problems and provide new theoretical basis and means of using the electronic computer to assist design.Using NMD method can not only shorten the design cycle, But also make full and reasonable use of frequency resources to effectively improve communication quality.
