摘要： The invention relates to a radio apparatus for estimating a direction from which a received wave arrives and forming a radio transmission channel between a transmitting end of the received wave and itself. The invention aims to maintain stable transmission quality. The radio apparatus of the invention includes: two receiving sections which alternately detect two received waves that have arrived from a same transmitting end to two elements, in every period as an integer multiple of a period of each symbol of the received waves; and an arriving angle calculating section which calculates, in every period, an arriving angle as an inverse function of a difference in two phases which are proportional to a distance between the two elements, given as a function of positions of the elements and the arriving angle of the received waves, and contain a difference in phase shift amounts of the two receiving sections.

摘要： A variation compensating unit that compensates an amplitude variation and phase variation efficiently and that improves system reliability and communication quality. A first combining section generates a first combined signal by combining signal on different transmission paths in which a variation has not occurred. A second combining section generates a second combined signal by combining signal on the different transmission paths in which a variation has occurred. A compensation value calculating section calculates compensation values for compensating variation according to the transmission paths on the basis of the first combined signal, the second combined signal, and signal on each transmission path in which a variation has not occurred or in which a variation has occurred. A compensating section compensates variation dynamically on the basis of the compensation values.

摘要： A high frequency amplifier containing: a constant envelope signal generation circuit for transforming an input signal to form two constant envelope signals where phases of the constant envelope signals correspond to an amplitude of an envelope of the input signal; two amplifying circuits for separately amplifying two constant envelope signals; and a power synthesizing circuit for synthesizing the first and second amplified signals to generate an amplified signal of the input electric signal, and reflecting remaining components of the first and second amplified signals which remaining components remain in the above synthesizing operation, toward the first and second amplifying circuits. Further, an input impedance of the power synthesizing circuit may be controlled by shifting phases of the above reflected components by respectively predetermined amounts, or by adaptively shifting phases of the above reflected components responding to an input level, so that a total efficiency of the high frequency amplifier is maximized. The high frequency amplifier may contain, instead of the above two amplifying circuits and the power synthesizing circuit, a circuit for inverting a phase of one of the two constant envelope signals; and a single-ended push-pull amplifier circuit for receiving the other of the two constant envelope signals, and an output of the phase inversion circuit, and synthesizing the received signals to generate an amplified signal of the input electric signal.

摘要： A wireless device selects another wireless device that is the relay destination of data and transmits data to a data collector that collects data. Then, the wireless device transmits data obtained by adding relay-destination-device identification information of identifying the another wireless device that is a relay destination to the same as data transmitted to the data collector to the selected wireless device that is the relay destination of data. Moreover, the wireless device transmits the received data to the data collector when data obtained by adding relay-destination-device identification information is received from another wireless device and the device itself corresponds to the relay-destination-device identification information.

摘要： A communications device using an adaptive antenna allows for adaptive control of the weights provided as an input to each antenna elements of the downlink based on uplink arrival angle information regardless of the difference between the uplink and downlink frequencies, and thereby increase the system capacity of the communications system. The communication device includes an downlink weighting calculator which extracts arrival angle information for each user from uplink user signal information, simulated user signals corresponding to each antenna branch which are generated in a simulated user signals generator and a downlink weighting calculator which controls based on the arrival angle of a desired user, and the weights of the downlink applied to the respective antenna branches, based on an arbitrary adaptive algorithm using these simulated user signals.
