摘要： A base station apparatus switches between a communication mode for performing communication with a communication party and a calibration mode for performing a calibration process. In the calibration mode, a weight vector in accordance with a first algorithm for performing a null steering directivity control for orienting an area of drastically-lowered antenna gain in the direction of arrival of a reception signal. Furthermore, multiple transmission signals weighted by the acquired weight vector are output, and a correction value for readjusting the result of the null steering directivity control is acquired from a control PC. In the communication mode, multiple transmission signals are corrected by using the correction value acquired in a calibration mode, and the corrected signals are output.

摘要： A slot of a low multiplicity is processed to narrow transmission timing intervals for already-connected users and thereby to make preparation for a new user, and a slot of a high multiplicity is processed to keep the maximum transmission timing intervals for the already-connected users so that the preparation for the new user is not performed. As a result, it is possible to provide the slot prepared for the new user while maximizing the transmission timing intervals. Further, the transmission timing intervals for the already-connected users are kept as large as possible during the traffic channel for preventing the deterioration of characteristics, and the shifting of the transmission timing is performed for the new user during the control channel so that the optimum transmission timing intervals can be achieved when the traffic channel is established. A DSP (14) executes the processing.

摘要： For each of a plurality of users having multiple connection to a specific time slot a synchronization window of a predetermined temporal length having a center corresponding to a synchronization position is set to disallow a subsequent signal reception outside the widow. Furthermore timings of transmission for users are controlled to prevent synchronization windows from overlapping or being too distant from each other in the time slot. Thus, synchronization positions can be prevented from approaching each other or having an inverted time relationship therebetween. This process is provided by a DSP in software.

摘要： A filler cap for a fuel tank is disclosed that can prevent environmental pollution and also improve fuel consumption without discharging fuel or harmful gas evaporated therefrom to an exterior of the fuel tank, until a pressure in the fuel tank reaches a predetermined value. In summary, immediately after attaching the filler cap to a fill opening, pressures are balanced between an interior and an exterior of the fuel tank. A spring raises a valve body and the rise/fall member, so that a lateral outer circumference of the valve body point contacts with plural convex portions of a second side wall, thereby closing the valve portion. In such a state, coming and going of a fluid between a first space and an opening is not allowed. When a pressure in the fuel tank reaches 5 kPa, the fluid rise a first air passage formed in spaces between respective convex portions on the second side wall, passing the valve portion. Rising fluid lowers the valve body to allow discharging an excessive pressure to the exterior of the fuel tank.

摘要： Filler cap for fuel tank which can further prevent environmental pollution without releasing harmful gas evaporated from fuel in fuel tank and can improve fuel efficiency is provided. When vaporized gas is generated in fuel tank, inner pressure of fuel tank is increased to pressure for deformation strength prescribed to valve body or more, a central part of valve body enters into third space thereby causing deformation so to shorten outer diameter of valve body to form wrinkles, and in peripheral part of valve body are formed a portion contacting to pivot of cylinder main body when deforming and concave portion not contacting thereto, second space and third space are connected via space of this concave portion and air passage channel formed in wall surface forming second space to release excessive pressure to outside fuel tank thereby bringing pressure inside fuel tank to lower than the pressure for deformation strength.

摘要： An adaptive array apparatus (100) that has a weight converge on an optimal value is provided. The adaptive array apparatus repeatedly adjusts the weight using predetermined calculations so as to minimize a difference between a desired signal and a combined signal which has been weighted with the weight. A parameter control unit (71) judges whether an adjusted weight is located closer to an optimal value than a reference value, and according to the judgment result, changes a step size which is used in the predetermined calculations performed by a reception weight calculating unit (72), to determine the extent to which the weight should be adjusted. With this construction, the adaptive array apparatus can increase convergence stability and speed in calculating a weight, and the weight converges on an optimal value.

摘要： A spatial multiplex base station (1000, 2000, 3000) estimates an optimal array parameter appropriate to a propagation environment of a received signal and changes the array parameter in an adaptive manner. The optimal value is estimated by referring to a table prepared in advance, by searching for the optimal value while executing an array process multiple times using different parameters, or by searching for the optimal value from the results of the previous frames. Consequently, a weight estimation sequential algorithm is executed based on the estimated array parameter. This enables realization of optimal signal reception in a radio receiving device, regardless of the propagation environment.

摘要： An FFT processing unit performs an FFT process on an OFDM signal received by a reception unit. Based on an output signal of the FFT processing unit, an interference wave level acquisition unit obtains a signal level of an interference wave in a unit radio resource not used by the base station with respect to each of a plurality of candidate timings for the reference timing in the base station. A reference timing adjustment unit determines a new timing of the reference timing from the plurality of candidate timings based on the signal level of the interference wave obtained by the interference wave level acquisition unit.
