摘要： In a frequency-division multiplexing transmitting apparatus for transmitting data at a frequency specific to a mobile station, a symbol compression and repetition unit compresses the time domain of each symbol of a transmit symbol sequence, repeats the symbol a prescribed number of times (L times) and rearranges the symbols of the obtained repetitive symbol sequence in such a manner that the symbols will have an arrangement identical with the arrangement of the transmit symbol sequence; a phase rotating unit applies phase rotation, which varies at a speed specific to the mobile station, to each symbol of the repetitive symbol sequence after the rearrangement thereof; and a transmitting unit transmits the symbols that have undergone the phase rotation. The phase rotating unit varies the amount of phase rotation, which is applied to each symbol of the repetitive symbols, in increments of k·2π/L (where k represents an integer specific to the mobile station) at the period of the repetitive symbol sequence.

摘要： A clock signal generating circuit generates a clock signal having a frequency other than frequencies obtained by dividing a predetermined frequency by natural numbers without using a PLL circuit. An oscillator generates a reference clock signal having a reference frequency. A counter counts the reference clock signal to divide the reference frequency of the reference clock signal. A count value output from the counter is reset when the count value reaches a predetermined number. Sine-wave data of a sine-wave is output when the count value is input, a set of the sine-wave data being output for successive numbers of the count value from zero to the predetermined number. The set of the sine-wave data corresponds to a predetermined number of waves of the sine-wave. A digital-to-analog converter converts the set of the sine-wave data into an analog sine-wave signal. A filter selectively filters a predetermined frequency component contained in the analog sine-wave signal. A comparator converts the analog sine-wave signal into a clock signal.

摘要： Tea leaves are extracted in warm or hot water, and the obtained extract is contacted with a cation exchange resin ionically bonded to potassium ion. The potassium ion is ionically bonded to the cation exchange resin in advance. Divalent ions in the tea beverage are replaced with the potassium ions from the cation exchange resin. The electrical conductivity of the extract is controlled in this whole process. The natural flavor and quality of the tea are thereby maintained more certainly, since metal ions that cause muddiness or precipitation are effectively removed.

摘要： A phase angle .theta. of a received signal is calculated according to a formula .theta.=tan.sup.-1 (Q/I), where I and Q are magnitudes of baseband signals obtained by quadrature detection of the received signal. An angular velocity .DELTA..theta. of the phase angle .theta. is also calculated. A variance parameter .SIGMA..sigma..sup.2 is calculated from a deviation .sigma.=.DELTA..theta.-.DELTA..theta., where .DELTA..theta. is a moving average of the .DELTA..theta.. The variance parameter .SIGMA..sigma..sup.2 thus calculated, is compared with a reference value to determine if a burst signal exists. Since the determination is performed essentially based on a phase of the received signal and not on an amplitude of the received signal, fluctuation of the amplitude of the received signal does not affect the decision.

摘要翻译： 根据公式θ= tan-1（Q / I）计算接收信号的相角θ，其中I和Q是通过接收信号的正交检测获得的基带信号的幅度。 也计算出相角θ的角速度ΔTATA。 方差参数SIGMA西格玛2由偏差σ=DELTAθ-DELTAθ计算，其中DELTAθ是DELTAθ的移动平均值。 将如此计算的方差参数SIGMA sigma 2与参考值进行比较，以确定是否存在突发信号。 由于基于接收信号的相位而不是接收信号的振幅来执行确定，所以接收信号的振幅的波动不影响该决定。
