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 application of Cosine Modulation Filter Bank (CMFB) technology in ultra-wideband wireless communication system, this paper mainly analyzes the technology of cosine modulation filter bank, and focuses on combining CMFB with multi-band orthogonal frequency division multiplexing (MB-OFDM) It is also analyzed that the CMFB technology can make full use of the spectrum resources more than the wireless communication system based on the traditional OFDM technology. Finally, it is proposed that the CMFB is an ideal technology for the UWB wireless communication system. UWB wireless communication system based on CMFB technology will be widely used.
