| abstract | Good MSK demodulation is performed regardless of phase fluctuations. [Solution] When demodulating a predetermined modulation signal (MSK modulation signal), the internal reference wave and the input signal (wobble signal) are multiplied, but the mutual phase state of the internal reference wave and the input signal is not shifted in phase. Adjust to converge. For this reason, a plurality of computing means (first to third multiplier integrators 31A, 31B, 31C) perform computations with different mutual phase states, and determine a system in the optimum mutual phase state from the computation results ( 38) The phase of the internal reference wave is adjusted so that the mutual phase state is given to a specific computing means (39, 36, 42). In particular, the optimum phase determination is performed appropriately by using the calculation result (integration result) in the STW modulation section or monotone section (no modulation section) of the input signal.
