摘　　要：提出了一种新的超宽带通信实现方式,该方式基于MB-OFDM技术,用户数据在时域和频域交织传输,形成了新的MB-TFI(时频交织)-OFDM方式。结合MBOA实际案例,分析了MB-OFDM芯片的商业化和产品化进程及前景展望。研究表明,MB-TFI-OFDMUWB技术以它独特的优势,将会促进MB-OFDM方案的发展,得到越来越多厂商的支持与应用,从而有希望成为WPAN物理层的标准技术。A novel mode of UWB communication based on MB-OFDM technology is proposed, in which the user data are interlaced in time and frequency domain during their transmission. According to the cases of MBOA, the process of commercialization of MB-OFDM chips is discussed. Research result indicates that due to the special advantages of MB-TFI-OFDM technology,MB-OFDM proposal will obtain supports from most of the manufacturers and is expected to become the standard of the physical layer of WPAN.
