基于有限域傅里叶变换的谱
Spread-Spectrum Based on Finite Field Fourier Transforms
摘要:
本文提出了一种基于有限域傅里叶变换的频谱系统。推导了定义在有限域上的正交扩频序列。本文还介绍了基于这种扩频系统的新型数字复用方案--多级码分复用。这些方案称为伽罗瓦域分复用(GDM)提供紧凑的带宽要求,因为只有领导者的分圆陪集需要被发送。
英文摘要:
Spread-spectrum systems are presented, which are based on Finite Field Fourier Transforms. Orthogonal spreading sequences defined over a finite field are derived. New digital multiplex schemes based on such spread-spectrum systems are also introduced, which are multilevel Coding Division Multiplex. These schemes termed Galois-field Division Multiplex (GDM) offer compact bandwidth requirements because only leaders of cyclotomic cosets are needed to be transmitted.
