Under the condition of indoor short-range wireless transmission, the UWB systems can provide very high data rate whereas the power consumption is very low, which makes it a promising candidate for wireless personal area networks (WPAN) where the data rate is greater than 110Mbps and the range is shorter than 10 meters in general. Moreover, UWB is also introduced into the underlying transport mechanism of wireless USB and wireless 1394 for even higher throughput up to 480Mbps within 2 meters [1]. The UWB systems based on MB-OFDM divide the whole assigned spectrum into several smaller sub-bands and each sub-band into a few subcarriers to transmit the information, which leads to lower design complexity as well as better spectral efficiency and fl exibility than the DS-UWB systems [1–3].
