摘要： To narrow the dynamic range of multicarrier signals and prevent both the increment of cost and the degradation of power efficiency. A modulating part (101) modulates transport data. An S/P converting part (102) performs an S/P conversion of a modulated symbol and outputs the modulated symbols, the number of which is the same as the number of all subcarriers, to an IFFT part (103) in parallel. The IFFT part (103) assigns the modulated symbols to the subcarriers, the frequencies of which are orthogonal to each other, to perform an inverse fast Fourier transform. A P/S converting part (104) performs a P/S conversion of the signals of time domain. When the instantaneous amplitude level of an OFDM signal is lower than a predetermined threshold value, a pit clip part (105) replaces this amplitude level by the predetermined threshold value. In other words, when the instantaneous power of the OFDM signal is close to zero, the pit clip part (105) converts a power value to a value that is greater than the actual power value.

摘要： A radio receiving apparatus wherein the interference can be minimized and the power and bands can be effectively used in the process of receiving a signal comprising a combination of an impulse signal and an OFDM signal. In this apparatus, a transmission path equalizing part (205) performs a transmission path equalizing process of a signal comprising a combination of an OFDM signal and an impulse signal of UWB-IR system, and a signal separating part (208) uses a constant (C) to clip the amplitude level for a signal (Y1) demodulated as the OFDM signal, and substantially clips only the signal components of the impulse signal. Further, only when a signal (Y2) demodulated as the impulse signal exhibits an amplitude level greater than the constant (C), it is outputted, while most of the signal power of the combined OFDM signal is removed.

摘要： A radio communication apparatus enabling reduction in peak-to-average power ratio without decreasing the transmission efficiency. In this apparatus, buffer section 103 temporarily stores input data prior to peak suppression. Peak detecting section 106 detects a peak with an amplitude level not less than a threshold. Peak cut section 107 reduces the detected peak to the threshold. Switching section 109 is switched so that the peak suppressed signal is output to FFT section 114 when the peak is detected, while the peak suppressed signal is subjected to transmission processing when the peak is not detected. Based on MCS information, signal recovering section 115 eliminates a signal assigned to a subcarrier set for MCS of a high level, and as a substitute, assigns the signal prior to peak suppression stored in buffer section 103. MCS setting section 116 selects MCS based on reception quality information of a communicating party.

摘要： A server (191) transmits image information consisting of basic data and complementary data to a router (100) through the Internet (192). The router (100) allocates the basic data to a BS (110) of a cellular system (193) and the complementary data to an AP (120) of a wireless LAN system (194). The BS (110) transmits the basic data to a MS (150) and the AP (120) transmits the complementary data to the MS (150). When the MS (150) is located in the area of the cellular system (193), the MS always maintains a communication channel with the BS (110) and when the MS enters the area of the wireless LAN system (194), the MS also opens a channel with the AP (120) while maintaining the channel with the BS (110). This allows the user to continue seamless communication.
