    The invention relates to a carrier wave recover device with multi-step structure, and relative method, wherein it comprises: a frequency correct multiple device for correcting the carrier wave frequency of digit transmission signal; one separator for separating the time domain synchronous head from the digit transmission signal; several frequency shift evaluators for inputting said synchronous head, via different shift evaluation methods, to evaluate the carrier wave frequency shift in different regions when resonating the digit transmission signal; and a composite unit for combining said frequency shift; and the carrier wave recover uses combined frequency shift to recover the carrier wave. The invention uses several frequency shift combined evaluations and one-step track circuit to avoid the device affected by multi-path signal channel to recover the carrier wave accurately.
