摘要： The universal platform for the SDR of the present invention employs the direct conversion approach with the n-port MMIC followed by reconfigurable reprogrammable devices such as DSP's or FPGA's. The universal platform is based on the linear operation of the devices. Thus, the DC offset problem may be solved. It is also possible to support very wide bandwidths compared with conventional I/Q receivers. Therefore, the present universal platform is suitable for multimode and multiband communications.

摘要： A high-performance demodulator for use in UWB (Ultra WideBand) multiple-access communication is disclosed. In a communication device, the correlation between a received signal corresponding to signals transmitted from a plurality of communication terminals by means of UWB (Ultra WideBand) communication and pulses at possible positions in a signal transmitted from each communication terminal is calculated. On the basis of the resultant calculated correlation, and taking into account interference among the signals transmitted from the communication terminals, the received signal is demodulated into original data issued by the respective communication terminals.

摘要： Signals received by antenna elements are respectively converted to lower frequency signals by the frequency converters. The lower frequency signals are then converted to the digital signals by A/D converters and supplied to a digital signal processing unit. The digital signal processing unit weights the digitized signals on the amplitude and the phase for each signal for optimally controlling the directivity. The weighted signals from the digital signal processing unit are converted to the analog signals by D/A converters and added by an adder. The added signal is then converted by a frequency converter to an original frequency of the received signals by the antenna elements.

摘要： The directional antenna apparatus of a base station, after sensing the direction of an undesired wave, calculates the optimum amplitude weighting coefficients and optimum phase weighting coefficients for a plurality of directions between the move starting point and move end point of a mobile station and creates a reference table. Then, when receiving a request for communication from the mobile station, the directional antenna apparatus reads weighting coefficients from the reference table, sets them in each antenna element, and points the directivity toward the mobile station, and starts communication. Then, calculating the time when the mobile station arrives at the position corresponding to each direction from the destination of the mobile station and its moving speed, and reads one by one the optimum amplitude and phase weighting coefficients from the reference table, and sets them in each antenna element, and communicates with the mobile station, while tracking the mobile station.

摘要： In an apparatus for controlling a multi-cylinder internal combustion engine with partial cylinder switch-off mechanism which is switchable between an all-cylinder operation mode in which all cylinders are operated and a partial-cylinder operation mode in which operation of partial cylinders is suspended, the operation of intake valves and exhaust valves is suspended or resumed in a predetermined order with respect to all of the suspended cylinders irrespective of a rotational frequency of the engine. There are provided a solenoid valve on an intake side and a solenoid valve on an exhaust side for switching input hydraulic pressures for hydraulically operated switching devices respectively on the intake side and on the exhaust side between the driving state and the drive-free state. At the time of switching the operation, one of the solenoid valves on the intake side and the exhaust side is driven in advance. The subsequent number of rotations of a crankshaft is counted. When the number of this counting has reached a predetermined value, the solenoid valve on the other side is driven.

摘要： An electronic component unit is provided with two electronic components which are disposed in parallel with each other and each of which has an internal electric circuit therein. Electrode pads are provided on the opposed surfaces of the two electronic components and are electrically connected to the internal electric circuits. The pads on one of the electronic components are respectively electrically and mechanically connected to the corresponding pads on the other electronic component by solder bumps. The areas of the pads increase or decrease stepwise in the direction from the central portions toward the outer peripheral edges of the two electronic components, while the volumes of the solder bumps are constant. Alternatively, the volumes of the solder bumps decrease or increase in the direction from the central portions toward the outer peripheral edges of the two electronic components, while the areas of all pads are constant. Each of the pads of the two electronic components is bonded to an associated solder bump over the whole area of the pad, whereby the shapes of the solder bumps respectively connected to the pads of the two electronic components change in the direction from the central portions toward the outer peripheral edges of the two electronic components to provide the solder bumps with different durabilities to stress, thereby assuring high reliability of the connection between the two electronic components.
