<P>PROBLEM TO BE SOLVED: To provide a reception detecting apparatus with a comparatively simple configuration discriminating whether a desired signal is receptible. <P>SOLUTION: Variable amplifier sections 44i, 44q for respectively amplifying an in-phase component and a quadrature component obtained by an orthogonal detection section 42 to a prescribed level, keep their amplification factors for a prescribed period. Thus, the products of the components of two BPSK signals are identical to each other. Thus, when the reception detecting apparatus receives the BPSK signal, an output of an integrator 50 is higher than a reference voltage Vref. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
