摘要： A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.

摘要： A processing unit generates timing information on timing, with which each of radio apparatuses is to synchronize in communication between the radio apparatuses when each of the radio apparatus broadcasts a signal, to control the communication between the radio apparatuses. A modem unit and the like broadcast the thus generated timing information. An RF unit and the like receive a signal which is synchronous with the timing information broadcast by them. When a signal which is asynchronous with the timing information and when the duration of this signal continues for a period longer than a first threshold value and the quality of this signal is more deteriorated than a second threshold value, a decision unit detects that the received signal is a disturbing signal. The modem unit and the like also broadcast to the effect that the disturbing signal has been detected.

摘要： A weight vector computing unit derives amounts of phase rotation for a plurality of multicarrier signals, respectively, and rotates the phase of a weight vector. A combining unit weights respectively a plurality of multicarrier signals with the phase-rotated weight vector, combines weighting results, and determines a combined result. A receiving weight vector computing unit remodulates the determined result and derives a first phase difference between the plurality of multicarrier signals and a result of the remodulation. The receiving weight vector computing unit remodulates the values of pilot signals and derives a second phase difference between the plurality of multicarrier signals and a result of the remodulation. Further, the receiving weight vector derives phase rotation amounts based on the first phase difference and the second phase difference.

摘要： An image frame input unit receives the input of image frames. An insertion unit inserts a plurality of markers into the image frame thus inputted. Each of the plurality of markers is defined as a pattern that is not scheduled to appear in data of the image frame. At this time, the insertion unit divides the image frame into a plurality of parts based on a data size storable in a radio packet, and inserts the markers among the divided parts of the image frame. An RF unit outputs the image frame into which the plurality of markers have been inserted.
