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： 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 wireless unit performs a frequency conversion process, a quadrature modulation process, and a quadrature detection process. A modem performs a modulation/demodulation process. A processing unit performs digital signal processing on a signal from the modem and on a signal to the modem. An image capturing unit acquires an external image and outputs the acquired image to a coding unit. The coding unit generates image data by performing a compression encoding process on the image received from the image capturing unit and outputs the image data to a control unit. The control unit controls the overall movement of a vehicle camera apparatus.

摘要： The control unit verifies whether or not the coded data of one frame has been transmitted within each frame period. When it hasn't, the control unit increases the compression ratio of a compression unit. When the coded data of one frame has been transmitted, the control unit compares the amount of coded data against a first and a second threshold value. When the amount of coded data is greater than or equal o the first threshold value, the control unit increases the compression ratio of the compression unit. When it is less than or equal to the second thresh hold, the control unit lowers the compression ratio of the compression unit.

摘要： A raw material formed by a mixture of, for example, soybean protein and water, is extruded by an extruder. Then, high-frequency electroconductive heating is performed by placing the material between a pair of electrodes and applying a voltage between the electrodes. As a result, a biodegradable molded article is obtained. In this method, biodegradable molded articles having a uniform structure are manufactured in a short period of time without increasing the cost of equipment or adversely affecting the working environment.
