摘要： A wireless communication apparatus is equipped with a plurality of antennas. A switch leads a received signal by way of an antenna selected according to an antenna switching signal to a demodulator unit. Software installed in a MAC unit generates a first switching signal. A diversity control unit generates a second switching signal by the built-in hardware circuit. The first switching signal is used as an antenna switching signal during a packet receiving ready period, while the second switching signal is used as an antenna switching signal during a period for receiving a packet.

摘要： It is an object of the present invention to provide a gain control circuit capable of reducing convergence time needed to stabilize the output level changing due to the fluctuations of an input level, maintaining the convergence time constant even if a signal with a different level is inputted to a variable gain amplifier and easily modifying a setting value even if the gain characteristic of the variable gain amplifier changes. A gain control unit normally adjusts the gain of a VGA according to a difference computed by a computation unit. If an input signal with a high level is inputted to the VGA immediately after receiving a packet and the output level of the VGA exceeds the threshold value of a step-down unit, the gain of the VGA can be forced to reduce by a prescribed value.
摘要翻译：本发明的目的是提供一种增益控制电路，其能够减少由于输入电平的波动而使输出电平变化稳定所需的收敛时间，即使输入了不同电平的信号，也保持收敛时间恒定到可变增益放大器，并且即使可变增益放大器的增益特性改变也容易地修改设定值。增益控制单元通常根据由计算单元计算的差异来调整VGA的增益。如果在接收到数据包之后立即将高电平的输入信号输入到VGA，并且VGA的输出电平超过降压单元的阈值，则可以强制VGA的增益减小预定值。

摘要： In a vehicle backward movement assisting apparatus for in-line parking, at a stop position of a vehicle, a seesaw switch is manipulated until an in-line guide line is superimposed on a target point which is a corner of a frame of a parking space, and a steering wheel is turned until the vehicle space mark is superimposed on the parking space, and the vehicle is moved backward while the steering angle of the steering wheel is held. When an eye mark is superimposed on the parking space, the vehicle is stopped, and the steering angle of the steering wheel is made maximum and the vehicle is moved backward, to thereby complete the in-line parking at the parking space.

摘要： Provided is a parking assistance apparatus utilizing a fixed target by taking an image thereof, the parking assistance apparatus being capable of recognizing the fixed target with high recognition accuracy while using simple image recognition processing. A mark (M) includes a plurality of illuminators (1). Sets of the plurality of illuminators (1) form characteristic points C1 to C4. Turn-ON request generation means (36) of a vehicle-side device (20) sequentially generates turn-ON requests for each characteristic point and transmits the generated turn-ON requests to a parking-lot-side device (10). A display control unit (11) of the parking-lot-side device (10) turns ON the characteristic points based on the turn-ON requests. An image recognition unit (31) of the vehicle-side device (20) performs image recognition for the characteristic points sequentially. Using the recognition result, positional parameter calculation means (34) of the vehicle-side device (20) calculates positional parameters of a camera with respect to the mark (M).

摘要： The purpose of the present invention is to simplify a circuit for carrying out an interleaving and a de-interleaving processing. A RAM address control outputs an address by an addition of an address output from an address ROM and a predetermined offset, based on state information. The address ROM stores address data corresponding to a rearrangement rule for data of each modulation system. A de-interleaving or an interleaving processing is accomplished by reading out of a RAM, or writing thereto, the data of an address specified by the RAM address control.
