移动通信调制技术的进展

移动通信发展过程中,特别是第3代移动通信发展中,移动通信调制技术相比传统的无线通信调制技术已有相当的变革和进展。文章就现代移动通信调制技术相位调制技术、频率调制技术、多进制调制技术、自适应调制技术进行讨论,并对相关技术性能和应用进行分析,最后提出对进一步发展的看法。

Evolution of Modulation Technology in MobileCommunications

In the development process of mobilecommunications especially the thir d -g en-eration mobile communications ,the modu-lation technique has underg one g rea t evo-lution from the traditional radio mo dulation.The paper discusses some modern modu-lation techniques :Phase Modulatio n,Fre-quency Modulation and Multi -Freque ncy Modulation,with analyses of their t echnical features and applications.Persona l views on the further development of the mod ula-tion technique are also provided at t he end of the paper.
