  • RADIO COMMUNICATION APPARATUS
    Publication number: 20120134447
    Abstract: According to one embodiment, an analog unit performs frequency conversion of a reception signal. A digital unit performs demodulation processing of the reception signal subjected to the frequency conversion by the analog unit. A PLL circuit generates a clock of the digital unit. A PLL-setting changing unit performs, based on the reception signal, a setting change of parameters of the PLL circuit to thereby control the jitter of the clock.
