    • It is provided a radio communication apparatus and radio communication method that, in the radio communication apparatus having a normal transmitting/receiving mode and a distortion correction mode, communicates successfully without influencing circuit characteristic in a normal transmitting/receiving mode, sends back a transmitting signal from the receiving system, extracts a distortion component due to narrowband characteristics or non-linear characteristics of a circuit, and corrects distortion in a distortion correction mode. In radio communication apparatus (100), distortion detecting section (111) extracts a distortion component using a transmitting baseband signal and a receiving baseband signal, coupling degree adjustment circuit (180) adjusts the degree of coupling between transmitting antenna (130) and receiving antenna (140), and coupling degree control section (170) switches the degree of coupling depending on a normal transmitting/receiving mode or a distortion correction mode.

    • A signal modulator that can control transmission power if level adjustment of a continuous signal from an oscillator is executed is provided. A pulse generator of one example of a signal modulator includes an oscillator, a control signal generator, a multiplier, a filter, and a control section. The oscillator and the multiplier are active circuits formed of active elements. A continuous signal is output from the oscillator and is input to the multiplier and the multiplier intermittently operates by a control signal output from the control signal generator, whereby a pulse signal is generated and the power level is easily adjusted by a signal from the control section.

    • There is a need for keeping the amount of data to be saved and a simulation process time almost constant irrespectively of a hierarchical level of a hierarchical circuit to be simulated. This simulation method includes a first process and a second process. The first process saves result data obtained from simulating an interface node between higher-level and lower-level hierarchies in accordance with a result of simulation using hierarchical circuit data hierarchized for multiple hierarchies. The second process uses result data saved by the first process to reproduce internal node data not saved by the first process. Result data for the interface node between hierarchies indirectly determines a value for the internal node. Result data to be saved is data concerning the interface node between hierarchies. The amount of saved data and the time needed for the second process are independent of a hierarchical level or a higher-level or lower-level hierarchy.
    • 需要保持要保存的数据量,并且模拟处理时间几乎恒定,而与待仿真的分级电路的分层级无关。 该模拟方法包括第一处理和第二处理。 第一个过程根据使用多层次层次化的分层电路数据的模拟结果,保存从模拟上级和下层层次之间的接口节点获得的结果数据。 第二个过程使用第一个进程保存的结果数据来再现第一个进程未保存的内部节点数据。 层次之间的接口节点的结果数据间接地确定了内部节点的值。 要保存的结果数据是关于层次结构之间的接口节点的数据。 保存的数据量和第二个进程所需的时间与层次级别或更高级别或较低级别的层次结构无关。
