  • Patent number: 7508795
    Abstract: During operation a check is made, by utilizing a tuning function of tuning communication parameters, if communication parameters used for wireless communication with another movable unit are suitable. When the communication parameters are found to be unsuitable, new communication parameters are used for communication. Thus, the communication performance of the movable unit is improved to significantly reduce the steps to select the optimum communication parameters and permits the communication parameter selection while confirming the reliability of each communication parameter.

  • Patent number: 6853837
    Abstract: A CDMA demodulator is disclosed, which comprises an AGC loop (13 to 20) including a IF signal converter (12) for converting a spread spectrum signal to an IF signal and an AGC amplifier (13) for variable gain amplifying the IF signal with a control voltage. The AGC loop also includes a power level calculating unit (17) for calculating the level of full power in the band of a channel under reception. Desirably, the power level calculating unit (17) starts the power level calculation from an instant corresponding to the forefront of slot. Desirably, the AGC loop further includes a control unit (18), which calculates control time based on the result of calculation in the power level calculating unit and feeds out a control voltage by calculating and controlling the control timing based on control amount. The power level calculating unit may start the power level calculation from an intermediate part of slot instead of the forefront thereof.

  • Patent number: 6853255
    Abstract: An AFC circuit compensates for an error of the oscillation frequency of a detecting oscillator based on a detection signal from a detector circuit. The detector circuit generates the detection signal at a timing tied to the oscillation frequency of said detecting oscillator. The AFC circuit has a frequency error determining circuit; a reference oscillator, a frequency error/control voltage conversion circuit; a PLL (phase lock loop) circuit; and a detecting frequency computing circuit. The reference oscillator is connected to provide an oscillator input to said PLL, and the PLL is connected to provide a control voltage to said detecting oscillator. The detecting oscillator is responsive to the control voltage for controlling the oscillation frequency thereof. The AFC circuit controls the oscillation frequency of the detecting oscillator based on the frequency error value so as to vary the oscillation frequency used as a sampling frequency of the detector circuit.

  • Publication number: 20040267983
    Abstract: A buffer managing unit 111 dynamically changes the capacity of the buffer allotted to a user memory 14, a buffer memory 15 and an external memory 16 based on the degree of communication control data changing with data of the environment of a radio network obtained form a communication data monitoring unit 118. The buffer managing unit 111 changes the threshold value of the buffer based on the degree of communication control data and, upon reaching of the threshold value of the buffer, limits the in-flow of data with respect to the external device. It is possible to prevent data loss without preparation of any wasteful memory space.
