Abstract (in Japanese) (See Japanese page) 
(in English) In this manuscript, an orthogonal frequency division multiplexing (OFDM) packet wireless communication system is implemented towards constructing a testbed for cooperative wireless communication systems. The system is composed of software defined radio (SDR) with universal software radio peripheral (USRP) and GNU Radio. OFDM modulation is constructed by the 1/4 scale model of IEEE 802.11a standard. The observed OFDM frequency spectrum is compared with the spectrum mask of IEEE 802.11a standard so that windowing is required to agree with it. Furthermore, the estimated channel state information (CSI) is shown in amplitude and phase spectrum to compensate the multipath fading. The experimental results show that the received sensitivity of -59 dBm attains at the packet error rate (PER) of 1% when subcarriers are modulated by quadrature phase shift keying (QPSK) and the received sensitivity of -61 dBm attains at 1% PER when subcarriers are modulated by binary PSK (BPSK).
