摘要： A PSK signal which is subject to frequency fluctuation and noise is demodulated through a quasi-coherent detection process with a fixed local frequency oscillator (5) noise elimination process using a low pass filter (17,18) after frequency adjustment, and a frequency and phase regeneration process using a PLL circuit (20). The PLL circuit (20) is updated by the estimated center frequency of a received signal by using an FFT (fast Fourier transform) circuit (11), a power spectrum means (12,13,14), and a frequency estimation circuit (15) estimating the center frequency based upon the fact that the modulated signal component exists only on a high level portion of the frequency spectrum.

摘要： A mobile communication system is disclosed which precludes the necessity for mobile station to perform processing for microcell zone switching even when it moves from one microcell zone to another and which permits high-speed microcell zone handover. The service area of mobile communication is split into a plurality of macrocells; the macrocells are each subdivided into a plurality of microcells; a microcell base station equipped with a transmitting and receiving antenna and a power amplifier is installed in each microcell; a different communication channel is assigned to individual mobile station in the macrocell; even when the mobile station moves from one microcell to another, no channel handover takes place; and only when the mobile station moves from one macrocell to another, a mobile network control center which supervises the macrocell base stations effects channel handover.

摘要： To a machining shape database, machining shapes are registered. A machining shape recognition function makes a comparison between CAD data from a CAD and the registered machining shapes, and extracts a matching registered machining shape. A machining method database stores information required to identify the machining method of a machining shape corresponding to the registered machining shape. Information about the machining method of the machining shape extracted by the machining shape recognition function is extracted by a machining step determination function from the machining method database, and machining methods are arranged in suitable order, whereby a machining step is generated.

摘要： An imaging apparatus (20) measures shake of the apparatus by a gyro sensor (9), performs “a center stop control” until receiving an instruction for start of recording the still picture, and performs “a lens correction control” after the start of exposure in the imaging apparatus. The center stop control controls the correction lens position so as to stop a correction lens at an optical axis center position which is a position of the correction lens at which an optical axis of the imaging lenses (1) coincides with an optical axis of a correction lens (2). The lens correction control controls the correction lens position so as to correct blurring of the image formed on an imaging element (3) on the basis of the measuring result. The imaging apparatus (20) returns the correction lens (2) to the optical axis center position before receiving a next instruction for start of next recording after completion of the exposure to the imaging element, and then performs the center stop control on the correction lens (2).

摘要： This invention provides a spread spectrum signal demodulator in which a noise component included in respective demodulation symbols is reduced and an effect of interference removal is further improved. Symbol decorrelating means detect correlations between spread codes allocated to spread spectrum signals to be removed and a receiving signal. A symbol deciding means 121 synthesizes one or the plurality of one symbol correlation values b1 to bk in common phase, namely, diversity-synthesizes them so as to decide a symbol. As the symbol decision, hard decision or soft decision can be used. Correlation modification means input the one symbol correlation values b1 to bk output from the symbol decorrelating means and the symbol decided result output from the symbol deciding means 121 thereinto, and modify the symbol correlation values b1 to bk. The modified symbol correlation values d1 to dk are transmitted into interference replicating means so as to be spectrum-spread by corresponding spread codes.
