摘要： Disclosed are a receiving device and a channel estimation method that are capable of using the amplitude information of a received signal to perform proper channel estimation. In the device, a detection section (102) extracts the amplitude information of the OOK modulation signal sequence in which a known CES (Channel Estimation Sequence) composed of data “0” and “1” is OOK (On Off Keying)-modulated to obtain a detected signal sequence. A “1”-detection section (1042) extracts only the sample value corresponding to the data “1” from the sample values of the detected signal sequence to obtain an extracted signal sequence. A correlation calculating section (1043) performs the correlation calculation between the extracted signal sequence and the CES. A propagation delay estimation section (1044) estimates the propagation delay amount of a CIR (Channel Impulse Response) from the correlation calculation. An amplitude coefficient estimation section (1045) estimates the amplitude coefficient of the CIR from the correlation calculation.

摘要： A system can suppress the degradation of the system's own throughput, while suppressing the interference with a different communication system sharing a frequency band with the system. In ST302, a base station selects a terminal (B) as a relay station. In ST305, the base station performs a separation between the subcarrier signals outside an FSS-used band and the subcarrier signals within the FSS-used band, and remaps the separated subcarrier signals within the FSS-used band to the subcarriers outside the FSS-used band. In ST306, the separated subcarrier signals outside the FSS-used band and the remapped subcarrier signals outside the FSS-used band are differentially transmitted at the same time. In ST308, the terminal (B) remaps signals received from the base station to the subcarriers within the FSS-used band and, in ST309, transfers those signals as remapped to a terminal (A). In ST310, the terminal (A) combines the signals transferred by the terminal (B) with signals received from the base station for decoding.
