    • A transmitter circuit includes a first synthesizer section, and a second synthesizer section which consumes less current than the first synthesizer section. The transmitter circuit performs switching such that the first synthesizer section is operated and the second synthesizer section is powered off in polar modulation, and the second synthesizer section is operated and the first synthesizer section is powered off in quadrature modulation, thereby reducing consumed power. While the first synthesizer section is operating, calibration for an oscillation frequency is performed, and when the operation is stopped, a calibration value is stored. When an operation of the first synthesizer section is restarted, the stored calibration value is corrected by using temperature change, thereby enhancing calibration accuracy and preventing degradation in quality of a transmission signal.
    • 发射机电路包括第一合成器部分和与第一合成器部分相比消耗更少电流的第二合成器部分。 发射机电路进行切换,使得第一合成器部分被操作,并且第二合成器部分在极性调制中被断电,并且第二合成器部分被操作,并且第一合成器部分在正交调制中被断电,从而降低了功耗。 当第一合成器部分工作时,执行振荡频率的校准,当操作停止时,存储校准值。 当重新启动第一合成器部分的操作时,通过使用温度变化来校正存储的校准值,从而提高校准精度并防止传输信号的质量劣化。

    • In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion α of a first computation amount, where the first adaptive control method has a first convergence rate and a first convergence error. Further, a computation unit computes weighting coefficients from initial values of the weighting coefficients computed by the computation unit, using a second adaptive control method in a proportion (1−α) of a second computation amount, where the second adaptive control method has a second convergence rate slower than the first convergence rate and a second convergence error smaller than the first convergence error. A controller controls determination of a ratio α/(1-α) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes.
