摘　　要：为了研究余弦调制滤波器组(CMFB)技术在超宽带无线通信系统中的应用,文中主要分析了余弦调制滤波器组技术,重点将CMFB与多频带正交频分复用(MB-OFDM)技术作比较,并且分析了基于CMFB技术比基于传统OFDM技术的无线通信系统更能充分利用频谱资源,最后提出CMFB是超宽带无线通信系统的一种理想技术。基于CMFB技术的UWB无线通信系统将会得到广泛的应用。In order to study the cosine modulated filter bank （CMFB） technology in the ultra-wideband wireless communications system, this paper analyzes in detail the technology of cosine modulated filter bank （CMFB）, compares the CMFB with MB-OFDM, and discusses the wireless communications system based on the CMFB, which is better than the wireless communications system based on the traditional OFDM technology in the full use of spectrum resources. Finally, this paper suggests that CMFB can be an ideal candidate for UWB system .The UWB system based on CMFB technique would be widely used in the future.
