频谱编码、频谱调制及其在变换域通信中的应用

频谱资源短缺是下一代高速无线通信面临的严峻问题,要求未来无线通信具有频谱动态访问能力.SMSE(频谱编码、频谱调制)框架把OFDM、MC-CDMA、TDCS等具有特定频谱结构的信号的分析合成纳入了统一的数学框架之内,在换域合成了具有自适应性及多样性的信号波形.文中介绍了SMSE的原理及设计参数,给出了TDCS的基本调制波形的参数取值:仿真表明,SMSE框是一种在变换域合成特定频谱结构波形的有效方法.

Application of Spectrally Modulated, Spectrally Encoded Theory in Transform Domain Communication

Spectrum resource scarcity is a serious challenge for next generation radios, and requires that the radios have the ability to dynamically access to the spectrum. The SMSE framework provides a uniform mathematical framework for the analysis and synthesis of OFDM, MC-CDMA, TDCS signals, and synthesizes the signal wave form with adaptability and diversity in transform domain. The paper tells of the SMSE principles and design parameters in detail, and then gives the parameters values for TDCS fundamental modul...
