摘要
首先介绍了 M带滤波器组的概念 ,然后给出基于此概念的 CMFB ( Cosine- Modulated FilterBanks)余弦调制滤波器组的设计及实现 ,并根据计算机仿真结果 ,与 DMT在性能和复杂度上作了比较。
In this paper, the theory of M band filter banks is firstly overviewed.Then the design and implementation method of the multi carrier modulation based on CMFB (Cosine Modulate Filter Bands) are presented.On the basis of computer simulation,the performance and complexity of CMFB are compared with those of DMT.
