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.

摘要： The synchronizing apparatus includes a block for detecting a code from an input signal, a block for detecting from the code the variable points of the code at several times as high as the symbol rate, a block for calculating a histogram of the detected variables of the code to time, and a block for deciding that the phase number at which the calculated histogram takes the maximum value is a symbol synchronization point. This synchronizing apparatus detects the zero-cross points of an intermediate frequency band signal at N times as high as the symbol rate. It also calculates a histogram of detected time (0 to N−1). The time (0 to N−1) at which the histogram is the maximum within a predetermined detected time is selected as a symbol clock, and thereby symbol synchronization is established.

摘要： An improved antenna arrangement for use in a cellular telecommunication system is provided. A plurality of antennas which are connected to a common base station are located on the periphery of a radio zone or cell. Each of the antennas has a directional characteristic oriented toward the center of the cell to cover the inside of the cell. This antenna arrangement minimizes the co-channel interference, thereby allowing the distance between cells to which the same channel is assigned to be shortened.
