| Abstract(in English) | In recent years, an Ultra Wideband-Impulse Radio (UWB-IR) system has attracted much attention in short range high speed wireless communications. Meanwhile, the single-carrier transmission with frequency domain equalization (SC-FDE) has also recently attracted much attention. It is reported that the SC-FDE system obtains an excellent performance as well as orthogonal frequency division multiplexing (OFDM) in the advantage of the frequency diversity gain even in strong frequency selective channels. However, in the SC-FDE system, the cyclic extension reduces the bandwidth efficiency. Thus, in the SC-FDE system, various methods that improve the bandwidth efficiency are reported. In this report, we evaluate the improvement of bandwidth efficiency based on cyclic prefix (CP) reconstruction as the method of improving bandwidth efficiency of UWB-IR and Direct Sequence (DS)-UWB. |
