CA 2076935

A non-coherent demodulator 1 multiplies a modulated intermediate frequency (IF) signal with a signal from a local oscillator 2 to produce a first pseudo baseband signal having frequency error. The first pseudo baseband signal is supplied to a wide band PLL type demodulator 15. A low-pass filter 26 removes noise component from a first control signal from a loop filter 19 in the wide band PLL type demodulator 15 to produce a second control signal. Multipliers 24 and 25 multiply the first pseudo baseband signal with an output of a voltage-controlled oscillator 27 controlled by a second control signal to produce a second pseudo baseband signal having smaller frequency error. The second pseudo baseband signal is supplied to a narrow band demodulator 14 and converted into a baseband signal.
